RRB JE ME (CBT I) Mock Test- 9 - Question 1

### If the rate of interest is 8% per annum and Rs. 10000 lent at the compound interest half yearly then calculate the equivalent simple rate of interest for the first year?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 1 Let the principal be Rs.100

the rate of interest is 8% per annum lent at the compound interest half yearly.

Compound interest for 6 months = 4%

Compound interest next 6 months = 4% + 4of 4% = (4 +.16)% = 4.16%

the equivalent simple rate of interest for the first year = 4 + 4.16 = 8.16%

RRB JE ME (CBT I) Mock Test- 9 - Question 2

### Three taps A, B, and C can fill a tank in 20, 24, and 30 hours, respectively. How long (in hours) would the three taps take to fill the tank if all of them are opened together?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 2 A can fill 1 unit of water in the tank in 1/20 hours

B can fill 1 unit of water in tank in 1/24 hours

C can fill 1 unit of water in tank in 1/30 hours

(A+B+C) can fill 1 unit of water in tank in 1/20+1/24+1/30 = 6+5+4/120 = 15/120 = 18 days

Therefore,

(A+B+C) can fill full tank in 8 days.

RRB JE ME (CBT I) Mock Test- 9 - Question 3

### PAB and PCD are two secants to a circle. if PA =10cm , AB =12cm and PC =11cm, then what is the value of PD?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 3

PA x PB = PC x PD

Let PD = X cm

10 x (10 + 12) = 11 x (11 + X) 11 + X = 20

X = 9

PD = 9 = 11 = 20 cm RRB JE ME (CBT I) Mock Test- 9 - Question 4

The speed of a boat in still water is 10 km/hr. It covers a distance of 50 km upstream in 6 hours. What is the speed (in km/hr) of the stream?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 4 Speed of boat = 10 km/hr

Upstream speed 50/6 = 25/3 km/hr  So, Downstream speed 35/3 km/hr. RRB JE ME (CBT I) Mock Test- 9 - Question 5

500 litres of milk solution has 40% milk in it. How much more milk should be added to make it 60% in the solution?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 5 Milk = 40% of 500 = 200 litres

Water is 60% of 500 = 300 litres

ATQ,

40%of mixture = water = 300 litres

New mixture quantity = 300/40% = 750 liters

The quantity of milk in the mixture = 60 % of 750 = 450 liters

Required milk to be mixed = 450 - 200 = 250 liters

Therefore,

250 liter of milk should be added to make it 60% in the solution.

RRB JE ME (CBT I) Mock Test- 9 - Question 6

The shadow of a tower on the ground level is increased by 20 m, when the angle of depression by the sun changes from 60 to 30. The height of the tower is?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 6 Let the height of tower DC = h meter

tan 600 = h/BC Putting the value of BC from equation(l) in equation (2), we get RRB JE ME (CBT I) Mock Test- 9 - Question 7

What will be the sum of all odd whole numbers between 10 and 38?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 7 To calculate sum, we need to find the number of odd whole numbers between 10 and 38 using the Arithmetic Progression formula.

That is,

Last term = First term + (number of terms-1) × Common difference

ATQ,

37 = 11 + (N-1) × 2

So, N or Number of terms = 14

Now,

Sum of terms = N/2 [2×first term(N−1)×d]

ATQ,

Sum = 14/2 [2×11+(14−1)×2]

Sum = 336

Therefore,

The Sum of all odd whole numbers between 10 and 38 is 336

RRB JE ME (CBT I) Mock Test- 9 - Question 8

A , B, and C invest in a business in the ratio 3:6:5. A and C are working partners. Only B is a sleeping partner; hence his share will be 3/4th of what it would have been if he were a working partner. If they make Rs. 50000 profit, half of which is reinvested in the business and the other half is distributed between partners, then how much does C get (in Rs)?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 9

Given the investment ratio old ratio

A : B: C

3 : 6 : 5

ATQ, total profit = 50000

after reinvestment the profit

= 50000/2 = 25000 RRB JE ME (CBT I) Mock Test- 9 - Question 10

The HCF and LCM of the two numbers are 45 and 270, respectively. If the ratio of the two numbers is 2:3 and the smaller of the two numbers is X, then find X2.

Detailed Solution for RRB JE ME (CBT I) Mock Test- 9 - Question 10 We know that

Product of numbers = product of lcm and hcf

2y × 3y = 45 × 270

y2 = 45 × 45

y = 45

then smaller no.

X = 2 × 45 = 90

X2 = (90)2 = 8100
