Question

in a hall theair are 200 chairs .the chair number of ram is divisible by 9 and 7.what would be the chair number of ram ?

Answer 1

Solution :-

In this question, we will have to find the LCM of 9 and 7 to find the chair number of Ram.

Prime factors of 9 = 3 × 3

Prime factors of 7 = 7 × 1

LCM of 9 and 7 = 3 × 3 × 7

= 63

Som chair number of Prathamesh would be any multiple of 63 which should be less than 200 because there are 200 chairs in the hall.

Multiples of 63 = 63, 126 and 189

So, the chair number of Ram would be 63 or 126 or 189
