### A tree of height 36m is on one edge of a road broke at a certain height.  It fell in such a way that the top of the tree touches the other edge of the road. If the breadth of the road is 12m, then what is the height at which the tree broke?

Detailed Solution for Aptitude Assessment I - Question 2

Let the tree was broken at x meters height from the ground and 36 - x be the length of other part of the tree.

From the diagram, (36−x)2=x2+122(36−x)2=x2+122
⇒1296−72x+x2=x2+144⇒1296−72x+x2=x2+144
⇒72x=1296−144⇒72x=1296−144
⇒x=16⇒x=16

Aptitude Assessment I - Question 4

A girl entered a store and bought x flowers for y dollars (x and y are integers). When she was about to leave, the clerk said, “If you buy 10 more flowers I will give you all for \$\$2, and you will save 80 cents a dozen”. The values of x and y are?

Detailed Solution for Aptitude Assessment I - Question 4

Given she bought xx flowers for yy dollars.

So 1 flower cost = yxyx

flowers or 1 dozen cost = 12yx12yx

Again, xx+10 cost = 2 dollars

1 flower cost = 210+x210+x

12 flowers or 1 dozen cost = 2×1210+x=2410+x2×1210+x=2410+x

Given that this new dozen cost is 80 cents or 4/5 dollar less than original cost.

⇒12yx−2410+x=45⇒12yx−2410+x=45

From the given options, c satisfies this.

Aptitude Assessment I - Question 6

The difference between the compound and simple interest on a certain sum for 2 years at the rate of 8% per annum is Rs.80,What is the sum?

Detailed Solution for Aptitude Assessment I - Question 6

Difference in simple and compound interest at the end of 2 years occurs because there is interest on first year interest. So Difference = P×(R100)2P×(R100)2
⇒ 80 = P×(8100)2P×(8100)2
⇒ P=80×(1008)2P=80×(1008)2 = 12,500

Aptitude Assessment I - Question 7

A ship went on a voyage. After it had traveled 180 miles a plane started with 10 times the speed of the ship.  Find the distance when they meet from starting point

Detailed Solution for Aptitude Assessment I - Question 7

Let the speed of the ship = m miles/hr. and plane took 't' hours to meet the ship

Then, m×t is the distance ship traveled after plane started

So we have, mt + 180 = 10mt

⇒ 9mt = 180

⇒ mt = 20

Hence distance = 180 + 20 = 200 miles

Aptitude Assessment I - Question 9

A 10 Liter mixture of milk and water contains 30 percent water. Two liters of this mixture is taken away. How many liters of water should now be added so that the amount of milk in the mixture is double that of water?

Detailed Solution for Aptitude Assessment I - Question 9

Two liters were taken away So we have only 8 liters of mixture.
Amount of milk in 8 liters of mixture = 8 × 70% = 5.6 liters
Amount of water in 8 lit of mix = 8 - 5.6 = 2.4 liters.
Half of milk i.e half of 5.6 = 2.8 liters.
We need (2.8 - 2.4) liters water more = 0.4 lit

Aptitude Assessment I - Question 10

X = 101102103104105106107......146147148149150 (From numbers 101-150). Find out the remainder when this number is divided by 9.

Detailed Solution for Aptitude Assessment I - Question 10

The divisibility rule for 9 is sum of the digits is to be divisible by 9. So

We calculate separately, sum of the digits in hundreds place, tenths place, and units place.

Sum of the digits in hundreds place: 1 x 50 = 50

Sum of the digits in tenths place : 0 x 9 + 1 x 10 + 2 x 10 + 3 x 10 + 4 x 10 + 5 x 1 = 105

Sum of the digits in units place : (1 + 2 + 3 + ...+ 9) x 5 = 225

So total = 380

So remainder = 380 / 9 = 2

Aptitude Assessment I - Question 11

The sticks of same length are used to form a triangle as shown below. If 87 such sticks are used then how many triangles can be formed?

Detailed Solution for Aptitude Assessment I - Question 11

First triangle is formed by using 3 sticks, but any subsequent triangle may be formed by using 2 sticks.  Therefore, If 1st triangles uses 3 sticks, Remaining sticks = 87 - 3 = 84.  With these 84, we can form 42 triangles. So total = 42 + 1 = 43
Shortcut:
To solve questions like these, use formula, 2n + 1 = k.  Here n = triangles, k = sticks
2n+1 = 87 ⇒⇒ n = 43.

Aptitude Assessment I - Question 12

On door A - It leads to freedom
On door B - It leads to Ghost house
On door C - door B leads to Ghost house
The statement written on one of the doors is wrong.
Identify which door leads to freedom?

Detailed Solution for Aptitude Assessment I - Question 12

Case 1: A, B are true. In this case, Statement C also correct. So contradiction.
Case 2: B, C are true. In this case, B leads to ghost house and C confirms it. Now A is wrong. So door A does not lead to freedom. So Door C leads to freedom.

*Multiple options can be correct
Aptitude Assessment I - Question 13

70, 54, 45, 41……. What is the next number in the given series?

Detailed Solution for Aptitude Assessment I - Question 13

Consecutive squares are subtracted from the numbers.
70 - 54 = 16
54 - 45 = 9
45 - 41 = 4
So next we have to subtract 1. So answer = 41 - 1 = 40

*Multiple options can be correct
Aptitude Assessment I - Question 14

If (p/q-q/p) = 21/10. Then find 4p/q+4q/p = ?

Detailed Solution for Aptitude Assessment I - Question 14

Let p/q = a, then (a - 1/a) = 21/10

⇒a2−1=a.2110 ⇒10a2−21a−10 = 0

Roots of the equation = −b±b2−4ac−−−−−−−√2a a = 21±441+400−−−−−−−−√20

a = 21±2920 = 5/2 or -2/5 For a = 5/2, 4p/q+4q/p = 58/5

For a = -2/5, 4p/q+4q/p = -58/5

*Multiple options can be correct
Aptitude Assessment I - Question 15

A man has a job, which requires him to work 8 straight days and rest on the ninth day. If he started work on Monday, find the day of the week on which he gets his 12th rest day.

Detailed Solution for Aptitude Assessment I - Question 15

He works for 8 days and takes rest on the 9th day. So On the 12th rest day, there are 9 x 12 = 108 days passed. Number of odd days = (108 - 1) / 7 = 107 / 7 = 2. So the 12th rest day is wednesday.

Detailed Solution for Aptitude Assessment I - Question 16

First if we count 1223334444. they are 10

In the next term they are 20

Next they are 30 and so on

So Using n(n+1)2×10≤2888

For n = 23 we get LHS as 2760. Remaining terms 128.

Now in the 24th term, we have 24 1's, and next 48 terms are 2's. So next 72 terms are 3's.

Aptitude Assessment I - Question 26

Direction: Question no. 26 to 30 are passage questions. Carefully read the passage and mark your answers.

Organisations are institutions in which members compete for status and power. They compete for resource of the organisation, for example finance to expand their own departments, for career advancement and for power to control the activities of others. In pursuit of these aims, grouped are formed and sectional interests emerge. As a result, policy decisions may serve the ends of political and career systems rather than those of the concern. In this way, the goals of the organisation may be displaced in favour of sectional interests and individual ambition. These preoccupations sometimes prevent the emergence of organic systems. Many of the electronic firms in the study had recently created research and development departments employing highly qualified and well paid scientists and technicians. Their high pay and expert knowledge were sometimes seen as a threat to the established order of rank, power and privilege. Many senior managers had little knowledge of technicality and possibilities of new developments and electronics. Some felt that close cooperation with the experts in an organic system would reveal their ignorance and show their experience was now redundant
