Question

A number consists of two digits.unit place is 8.if we reversed the digits,the no. So formed is 7/4 the whole number.find the number.

Answer 1

Answer:

Given that the unit place digit of the number is 8

Let the tens place digit of the number be x.

Then, original number = 10x + 8

After reversing the digits,

New number = 80 + x

According to the question;

New number is 7/4 th of original number.

=> 80 + x = (7/4)(10x + 8)

=> 4(80 + x) = 7(10x + 8)

=> 320 + 4x = 70x + 56

=> 70x - 4x = 320 - 56

=> 66x = 264

=> x = 264/66

=> x = 4.

Thus,

The number is (10x + 8)

ie, (10•4 + 8)

ie, (40 + 8)

ie, 48.
