1. The difference of two numbers is 1365. On dividing the larger number by the smaller, we get 6 as quotient and 15 as remainder. What is the smaller number?
a) 1635
b) 270
c) 290
d) 1700
Answer: (b)Explanation: Suppose the smaller number is x, then the larger number = (x+ 1365)
Therefore, x+1365 = 6x+ 15 5x = 1350 x = 270.
Thus, the smaller number = 270.
b) 270
c) 290
d) 1700
Answer: (b)Explanation: Suppose the smaller number is x, then the larger number = (x+ 1365)
Therefore, x+1365 = 6x+ 15 5x = 1350 x = 270.
Thus, the smaller number = 270.
a) 10100
b) 10111
c) 10001
d) 10101
Answer: (d)
Explanation: The smallest five digit number is 10000

a) 64
b) 60
c) 55
d) 52
Answer: (a)
Explanation: The mean marks of 10 men = 70
Total marks of 10 men = 70 × 10 = 700
The mean marks of 15 women = 60
Total marks of 15 women = 60 × 15 = 900
∴ Sum of the total marks of 25 people = 700 + 900 = 1600
a) 64
b) 60
c) 55
d) 52
Answer: (a)
Explanation: The mean marks of 10 men = 70
Total marks of 10 men = 70 × 10 = 700
The mean marks of 15 women = 60
Total marks of 15 women = 60 × 15 = 900
∴ Sum of the total marks of 25 people = 700 + 900 = 1600
∴ The mean marks of all the 25 people =1600/25=64

a) Rs. 9
b) Rs. 4
c) Rs.8
d) Rs.6
Answer: (b)Explanation: The customer pays Rs. 63 after a discount of 10%.
If the list price is Rs. x, then
X – 10% of x = 63
X = Rs. 70
Therefore, the list price = Rs. 70
The retailer buys the article at 30 % discount
= 70 – 30 % of 70
=Rs. 59
Then the profit for the retailer = Rs. (63 -59) = Rs.4.

a) Rs. 9
b) Rs. 4
c) Rs.8
d) Rs.6
Answer: (b)Explanation: The customer pays Rs. 63 after a discount of 10%.
If the list price is Rs. x, then
X – 10% of x = 63
X = Rs. 70
Therefore, the list price = Rs. 70
The retailer buys the article at 30 % discount
= 70 – 30 % of 70
=Rs. 59
Then the profit for the retailer = Rs. (63 -59) = Rs.4.

Cost price as a percentage of selling price = (100/45 × 100) = 222.22%.
a) 10.5
b) 11.5

(a) 5 seconds
(b) 6 seconds
(c) 2 seconds
(d) 10 seconds
Answer: (a)
Explanation:
Time = Length of the train/ Relative speed between the two bodies
Relative speed= 120 – 12 = 108 kmph
Converting kmph to mps,

Time= 150/30
(a) 5 seconds
(b) 6 seconds
(c) 2 seconds
(d) 10 seconds
Answer: (a)
Explanation:
Time = Length of the train/ Relative speed between the two bodies
