Question

2. The seven-digit number 876p37q is
divisible by 225. The values of p and q
can be respectively
(a) 9,0
(6) o, o
(c) 0, 9
(d) 9,5​

Answer 1

Answer:

d

Step-by-step explanation:

for the no. to be divisible by 9, the sum of its digits must be divisible by 9 and for the no. to be divisible by 5, its final digit must be 5 or 0. hence, the only possible option is d.

Answer 2

Answer:

I think the answer may be (d) 9,5

Step-by-step explanation:

it is because for the number to be divisible by 225, it should be divisible by 15 so, should be divisible by 3 and 5 .

by divisibility rule of 5 the last digit (i.e., q) should be 5

also, by divisibility of 3 8+7+6+p+3+7+q = multiple of 3

We got the value of q as 5 . and can get value of p by solving above equation
