Answer & Explanation

1. (2)

A*(90/100) = (B*30)/100

= A x 3 = B

= A x x% = A x 3 = (x/100) = 3

x = 300

2. (3)

Required percentage  = (40*100+50*90+60*80)/(40+50+60) = 88.66%

3. (1)

Let y be 100

x = 75

Required percent  = (25*100)/75 = 33.33%

4. (4)

Fourth number = (4×4+4×4 – 3×7)

= (16 + 16-21) = 11

5. (3)

If the smallest number be x, then

(x/3)+12 = x+2

x + 36 = 3x + 6

3x –  x  = 36-6

2x = 30

x =15

third number = 15 + 4 = 19

6. (1)

7. (3)

Speed of the first train = 120/10 = 12 m/sec.

Speed of the second train =120/15= 8 m/sec.

Relative speed = (12 + 8) = 20 m/sec.

Therefore Required time =(120 + 120)/20  = 12 sec.

8. (1)

Let Arun’s weight by X kg.

According to Arun, 65 < X < 72

According to Arun’s brother, 60 < X < 70.\

According to Arun’s mother, X <= 68

The values satisfying all the above conditions are 66, 67 and 68.

Required average = 66 + 67 + 68/3 = 201/3   = 67 kg.

9. (4)

L.C.M. of 252, 308 and 198 = 2772.

So, A, B and C will again meet at the starting point in 2772 sec. i.e., 46 min. 12 sec.
