Number System Practice Test 2

Question : 12 of 40

Marks: +1, -0

A number lies between a square of 35 and 36. Find the number if it is a multiple of squares of 4 and 5.

Solution:

Let the number be x

35^2 < x > 36^2

1225 < x > 1296

4^2×5=80

So, 80 is the multiple of the number.
∴ 80 × 16 = 1,280 is the only possible number.
