6. What is the product of all the numbers in the dial of a telephone?
A.1,58,480
B.1,59,450
C.1,59,480

7. At the end of a business conference the ten people present all shake hands with each other once. How many handshakes will there be altogether?
A.20

A.48
B.44
C.42
D.40
Let number of girls = x and number of boys = 3x. Then 3x + x = 4x = total number of students. Thus, to find exact value of x, the total number of students must be divisible by 4.

9. If you write down all the numbers from 1 to 100, then how many times do you write 3?
A.11
B.18
C.20
D.21
Clearly, from 1 to 100, there are ten numbers with 3 as the unit’s digit – 3, 13, 23, 33, 43, 53, 63, 73, 83, 93; and ten numbers with 3 as the ten’s digit – 30, 31, 32, 33, 34, 35, 36, 37, 38, 39. So, required number = 10 + 10 = 20.

A.2
B.3
C.4
D.5
Let d and s represent the number of daughters and sons respectively. Then, we have: d – 1 = s and 2 (s – 1) = d Solving these two equations, we get : d= 4, s = 3.
