In following questions, one term in number series is incorrect.

Find out the incorrect number 10, 14, 28, 32, 64, 68, 132

Find out the incorrect number 10, 14, 28, 32, 64, 68, 132

Alternately, the numbers are increased by four and doubled to get the next number>

Thus, 10 + 4 = 14;

14 * 2 = 28;

28 + 4 = 32;

32 * 2 =64 and so on.

So, 132 is wrong and must be replaced by (68 * 2) i.e. 136..

A movie theatre sold 5 times as many children's tickets as adult tickets to an afternoon show. If 132 tickets were sold in all, how many were children's tickets?

Adult tickets : X

Children ticket: 5 x

5 x + X = 132

x = 132/6

X = 22

Children tickets: 5 x

5(22 )= 110
