13. Let N be the greatest number that will divide 1305, 4665 & 6905 leaving the same remainder in each case. Then sum of digit in N is?

(1) 4
(2) 5
(3) 6
(4) 8

Correct Answer: (1) 4

Solution:N = HCF of (4665-1305),

(6905-4665) ог, (6905-1305)

=HCF of 3360, 2240, 5600 =1120

Sum of digit of N = (1 + 1 + 2 + 0) = 4

14. On selling 17 balls at Rs. 720 there is loss equal to cost price of 5 balls. The cost price of a ball is.

(1) 45 Rs.
(2) 50 Rs.
(3) 60 Rs.
(4) 55 Rs.

Correct Answer: (4) 55 Rs.

Solution:17CP - 17SP = 5CP

⇒12CP = 17SP = 720

16. The ratio between the speed of two train is 7:8. If the second train runs 400 km in 4 hours, then the speed of the first train is.

(1) 70 km/hr.
(2) 75 km/hr.
(3) 84 km/hr.
(4) 87.5 km/hr.

Correct Answer: (4) 87.5 km/hr.

Solution:Speed of second train = 400/4 =100 km/hr.

let speed of first train = x

∴ 7/8 = x/100

⇒ x = 87.5km / hr.

17. In one hour a boat goes 11 km along the stream & 5 km against the stream. The speed of the boat in still water in km/hr is

(1) 3 km/hr.
(2) 5 km/hr.
(3) 8 km/hr.
(4) 9 km/hr.

Correct Answer: (3) 8 km/hr.

Solution:Downstream speed = 11 km/hr.

Up stream speed = 5 km/hr.

Speed of boat in still water = 1/2 (11 + 5) = 8km / hr .

18. The value of 0.1 x 0.1×0.1+0.2×0.2×0.2/0.2×0.2×0.2+0.4×0.4×0.4

(1) 0.0125
(2) 0.125
(3) 0.25
(4) 0.5

Correct Answer: (4) 0.5

Solution:Let, 0.1 = a

0.2 = b

a*a*a + b*b*b/2(a*a*a) + 2(b*b*b)

=1/2 (1) = 0.5
