# Two numbers have a ratio of 5:7 and product of them is 2835. These numbers are:

- 45, 63
- 35, 81
- None of these
- 39, 65

**Answer: (1) 45, 63**

**Explanation:-**

The ratio of two numbers = 5: 7

Let the two numbers be 5 X and 7 X

The product of the two numbers = 2835

Then, 5 X x 7 X = 2835

35 X^2 = 2835

X^2 =2835/35

X^2 = 81

The square root on both side,

X = 9

The two numbers are 5 X = 5 x 9 = 45 and 7 X = 7 x 9 = 63

Then, the two numbers are 45, 63.

Hence, the answer is (1) 45, 63.
