Three cubes of edges 6 cms, 8 cms and 10 cms are meted without loss of metal into a single cube. The edge of the new cube will be:
1. 8 cms
2. 12 cms
3. 14 cms
4. 16 cms
Answer: Option B
Volume of new cube = Volume of cube 1 + cube 2 + cube 3 = 6³ + 8³ + 10³, = 216 + 512 + 1000
a³ = 1728,
a = (1728)^1/3 = 12

If 378 coins consist of rupee, 50 paise and 25 paise coins, whose values are proportional to 13 :11 : 7, the number of 50 paise coins will be :
1. 128
2. 132
3. 133
4. 136
Answer: Option B
If values are proportional to 13 : 11 : 7, then the number of coins will be proportional to 13/1 : 11/0.50 : 7/0.25 ⇒ 13 : 22 : 28. Now from this the number of coins of 50 paise will be 378 × 22/63 = 132.
A person travels 48 kms at 12 kms/hour and further 48 kms at 16km.s/hour. His average speed for the whole
1. 14 km/hour
2. 13(4/7)km/hour
3. 12(5/7)km/hour
4. 13(5/7)km/hour
Answer: Option D
Avg. Speed = (Total Distance / Total Time)
TD = 48 + 48= 96,
T₁ = 48/12 = 4hrs
T₂ = 48/16 = 3hrs
T₁ + T₂ = 4 + 3 = 7
Avg Speed = 96/7 = 13(5/7) km/hr

Simplify (0.001344 / 0.3 x 0.7) = ?
1. 0.0064
2. 0.064
3. 0.64
4. 6.4
Answer: Option A
(0.001344 / 0.3 x 0.7) = 0.0064
The difference of two numbers is 11 and one fifth of their sum is 9. The numbers are :
1. 31, 20
2. 30, 19
3. 29, 18
4. 28, 17
Answer: Option D
x − y = 11, x + y = 5 × 9 x − y = 11, x + y = 45, y = 17, x = 28

A reduction of 20% in the price of mangoes enables a person to purchase 12 more for Rs. 15. What was the price of 16 mangoes before reduction of price ?
1. Rs. 6
2. Rs. 5
3. Rs.7
4. Rs. 9
Answer: Option B
Price x Consumption = Expenditure
Consumption = Exp. Price
(15 / 8x) - (15 / x) = 12
x = (15 x 2) / (12 x 8)
For 16 Mangoes = [(15 x 2) / (12 x 8)] x 16 = 5
