QUESTION: 2

Four of the five parts named (A),(B),(C),(D) and (E) in the following equation are exactly equal. Which of the parts is not equal to the other four? The name of that part is the answer.

Solution: All equations are resulting 2x2 - 3xy + y2
except (B) gives
2x2 - xy - y2
QUESTION: 3

x2(y - z) + y2(z-x) + z2(x - y) can be factorised as

Solution: x2 (y - z) + y2 (z - x) + z2 (x - y)
= x2y - x2z + y2z - y2x + z2x - z2y
= xy(x - y) - xz (x - y) - zy (x - y) + z2 (x - y)
= (x - y) [xy - xz - zy + z2]
= (x - y) [x(y - z) - z (y - z)]
= (x - y) (y - z) (x - z)
= - (x - y) (y - z) (z - x)
QUESTION: 4

In a certain party,there was a bowl of rice for every two guests,a bowl of broth for every three of them and a bowl of meat for every four of them. If in all,there were 65 bowls of food,then how many guests were there in the party?
Solution:

Let the number of rice bowls be x, number of broth bowls be y
and number of meat bowls be z
∴ x + y + z = 65 .....(1)
and 2x = 3y = 4z .....(2)
By solving both the equation we get x = 30, y = 20 and z = 15 So, number of guests = 30 × 2 = 20 × 3 = 15 × 4 = 60

∴ They will meet for the first time after

QUESTION: 8

The sides of a triangle are in the ratio 13:14:15 and its perimeter is 168cm. The length of the altitude corresponding to the longest side is
Solution:

Ratio of sides = 13 : 14 : 15
Perimeter of triangle = 168 cm
Let the sides are 13x, 14x, and 15x
∴ 13x + 14x + 15x = 168
⇒ 42x = 168
⇒ x = 4
∴ sides are 13 × 4 = 52 cm
14 × 4 = 56 cm
15 × 4 = 60 cm

QUESTION: 9

The average weight of a class of 24 students is 35 kg. If the weight of the teacher be included, the average rises by 400 g. The weight of the teacher is:

QUESTION: 11

A sum of money lent out at simple interests amounts to Rs. 720 after 2 years and to Rs. 1020 after a further period of 5 years. The sum is :
Solution:

Principal + SI for 2 years = Rs 720 ……(I)
Principal + SI for 7 years = Rs 1020 ……(II)
Subtracting equation (I) from (II),
S.I. for 5 years = (1020 – 720) = Rs 300
∴ S.I. for 2 years = 300 x 2/5 = Rs 120
∴ Principal = (720 – 120) = Rs 600

Solution:



Let the side of square be x unit.
sider the right triangle ABD
have x2 + x2 = (10 + 10)2
⇒ 2x2 = 400
x2 = 200
Area of square = 200 sq units
One of circle = πr2 = 22/7 x (10)2 = 314 sq units
One of shaded region not included in square
= 314 sq unit - 200 sq unit
= 114 sq unit.

QUESTION: 20

ABC is a triangle. ∠A = 80º, ∠C = 60º. The measure of (yº - xº) is
Solution:


∠ABC = 180º - (∠BAC + ∠ACB)
∠ABC = 180º - 140º
∠ABC = 40º
But ∠ABC = 2xº
⇒ 2x = 40º
⇒ xº = 20º
Hence,
∠BOC = 180º - (20º + 30º)
∠BOC = 130º
⇒ yº - xº = 130º - 20º
yº - xº = 110º

QUESTION: 30
An alloy contains copper and Zinc in the ratio 5:2 and another alloy containing Zinc and tin in the ratio 3:4. If two parts of first alloy and one part of second alloy are melted together to form a new alloy of copper,zinc and tin, the ratio of metals in the new alloy will be
Solution: Allay A contains Copper and Zinc in the ratio 5 : 2
Alloy B contains Zinc and tin in the ratio 3 : 4
The new alloy contains 2 parts of alloy A that means copper and zinc ratio is 10 : 4
And
One part of alloy B that means zinc and tin ratio is 3 : 4
So copper = 10
Zinc = 4 + 3 = 7
tin = 4
So the ratio of metals in the new alloy will be 10 : 7 : 4
