Answers :

1) Answer: d)

2) Answer: b)

R+W=232

4R-W=538

Solving these equations we get, R=154

W=232-154=78

3) Answer: b)

(m*d1*h1)/w = (w*d2*h2)/w

5*24*5 = w* 25*3

W=24/3 = 8 women

4) Answer: c)

S = d/t

T = 100/( 30*(5/18))

= 12 sec

5) Answer: d)

6) Answer: d)

A + D= 15+3=18

(18/100)*360 = 64.8°

7) Answer: a)

Answer: a)

81+9.2=17.3

17.3+9.2=26.5

26.5+17.3=43.8

43.8+26.5=70.3 ->71.5

70.3+43.8=114.1

So. 71.5 is wrong

Direction (9-10) :

9) Answer: b)

Hence the wrong number is 521

10) Answer: a)

422/12= 1764/12= 147
