Answers :

1) Answer: A

747.03 ÷ √6890 + √170 * 16.91 – 26.16 * √65 =?

747 ÷ √6889 + √169 * 17 – 26 * √64 =?

9 + 221 – 208 =?

22 =?

2) Answer: C

(13.07)² + (29.93)² – (23.314)² =?

13² + 30² – 23² =?

169 + 900 – 529 =?

540 =?

3) Answer: A

(1710.01 ÷ √3250) – (13.19 * 1.991) =? ÷ √65

(1710 ÷ √3249 – (13 * 2) =? ÷ √64

30 – 26 =?/8

? = 32

4) Answer: C

29.91% of 580.07 + 21.181 % of 199.91 =? + √2115

30/100 * 580 + 21/100 * 200 =? + √2116

174 + 42 =? + 46

? = 170

5) Answer: A

38.91 * 4.99 – 12.04 * √35 + 9.14 * 2.902 =?

39 * 5 – 12 * √36 + 9 * 3 =?

195 – 72 + 27 =?

150 =?

6) Answer: B

Ratio of the ages of A, B, C, D and E = 12: 15: 18: 12: 8

18x + 12x = 60

30x = 60

x = 2

Required average = ((12 + 15 + 18 + 12 + 8) * 2)/5

= 26 years

7) Answer: C

4x/(x + 25) = 16/9

16x + 25 * 16 = 36x

20x = 400

x = 20

Total quantity = 20 * 5 = 100 liters

8) Answer: A

Boys = 200 * 13/20 = 130

Girls = 200 * 7/20 = 70

Average weight of class = (130 * 40 + 70 * 30)/200

= 36.5 kg

9) Answer: D

Area of rectangle A = 12 * 18 = 216 cm²

Area of rectangle B = 216/2 = 108

Length of rectangle B = 108/9 = 12 cm

Perimeter of rectangle B = (12 + 9) * 2 = 42 cm

10) Answer: B

Required time = (300 + 360)/((60 + 72) * 5/18)

= 18 seconds
