C. 64
D. 98Edges of a cuboid are in the ratio 1 : 2 : 3 and its sunface area is 88 cm2. The volume of the cuboid is ?
A. 48 cm3
B. 120 cm3
C. 24 cm3
D. 64 cm3A boat having a length 3 m and breadth 2 m is floating on a lake The boat sinks by 1 cm when a man gets on it. The mass of man is ?
A. 72 kg
B. 96 kg
C. 12 kg
D. 60 kgCapacity of a cylindrical tank is 246.4 litres. If the height is 4 metres, what is the diameter of the base?
A. 2.8 m
B. 14 m
C. 1.4 m
D. None of themRadius of the cylinder is half its height and area of the inner part is 616 sq. cms. Approximately how many litres of milk can it contain?
A. 1.7
B. 1.9
C. 1.5
D. 1.4x is 20% more than z and y is 80% more than z. Find x:y ?
A. 2:3
B. 1:3
C. 1:4
D. 3:4x = z+(20/100)z = 1.2z y = 1.8z x:y = 1.2z:1.8z = 12:18 = 2:3
A, B, C and D divide a sum of money among themselves in the ratio 7:4:3:2. If D gets Rs. 500 less than A, find the total amount ?
A. Rs.340
B. Rs.780
C. Rs.100
D. Rs.1600Two kinds of rice, 1st costs Rs.13 per kg and 2nd costs Rs.19 per kg are mixed together. Find the ratio in which the 2 types are mixed so that the mixture costs Rs.14.2 per kg ?
A. 3:4
B. 4:3
C. 4:1
D. 3:1Therefore, 13x + 19(1-x) = 14.2
13x -19x + 19 = 14.2
4.8 = 6x
x = 0.8 ; (1-x) = 0.2
Therefore, the ratio is 0.8 : 0.2 = 4:1X, Y and Z are quantities of the same kind such that X:Y=5:8 and Y:Z=4:7. Find X:Z ?
A. 5:14
B. 5:7
C. 32:35
D. 67:56X:Z=(X:Y)*(Y:Z) =(5:8)*(4:7) = (5/8)*(4/7) = 5/14
