Question 54

If 347P is divisible by 9, then what is the value of P?

Solution

If a number is divisible by 9, then the sum of its digits must also be divisible by 9.

Number : 347P

Sum of digits = $$3+4+7+P=(14+P)$$

Now, for above value to be divisible by 9, it should be equal to 18 (next highest multiple of 9)

=> $$14+P=18$$

=> $$P=18-14=4$$

=> Ans - (C)
