KEY & SOLUTION

MATHEMATICS

01. (A) Cost of 1 bag + 1 T-shirt = 200
Cost of 4 bags + 2 T-shirts = 650
Cost of 4 bags + 4 T-shirts = 4 × 200 = 800
2 T-shirts = 800 – 650 = 150
1 T-shirt = 150 ÷ 2 = 75
1 bag = 200 – 75 = 135
2 bags = 2 × 135 = 270
75 + 270 = 355
Cost of 1 T-shirt and 2 bags = 355
02. (A) At first chickens : cows In the end chickens : cows
5:6 3:2
10 : 6 9:6
10 units – 9 units = 1 unit
1 unit = 300
10 units – 6 units = 4 units
4 units = 4 × 300 = 1200
There were 1200 more chickens than cows at first.
03. (A) Sunil : 60 units, Manish : 100 units
100 units = 70
1 unit = 70 ÷ 100 = 0.7
60 units = 60 × 0.7 = 42
Manish : 70 parts, Dinesh : 100 parts
70 parts = 70
1 part = 70 ÷ 70 = 1
100 parts = 100 × 1 = 100
100 – 42 = 58
Dinesh scored 58 more marks than Sunil
04. (B) Total number of participants = 240 + 560 = 800
240
Percentage of girls = × 100% = 30%
800

05. (D) Let the base of a triangle be 1 unit
Total number of units of the rectangle = 5 + 2 + 5 + 2 = 14
14 units = 280
1 unit = 280 ÷ 14 = 20
2 units = 2 × 20 = 40
5 units = 5 × 20 = 100
Area of rectangle ABCD = 40 × 100 = 4000 cm2
4000 ÷ 2 = 2000
The area of the shaded parts of rectangle ABCD is 2000 cm2

REASONING

01. (C) There are 3 meaningful words are formed.
