When 96 is added to a $N^2$ , it gives another perfect square. If N is a natural no., how many distinct values of N are possible?
Answer: (b)
$N^2 + 96 = P^2$ , or, 96 = $P^2 – N^2$.
Now factorize 96 and equate it with (P + N) (P – N).
If 653xy is divisible by 80 then the value of x + y is
Answer: (d)
Since 80 = 8 × 10 or 80 = 16 × 5
Thus y (i.e., unit digit) must be zero.
∴ 653xy = 653x0, where 653x0 must be divisible by 16 or 653x is divisible by 8.
Thus the last 3-digit number 53x will be divisible by 8.
Hence, at x = 6, we get the required result.
∴ x + y = 6 + 0 = 6
