Question

Ramesh thinks of a number and subtract 5/2 from it. He multiplies the result by 4. The final result is 3 times his original number. Find the number.​

Answer 1

Answer:

let the no. be x

a / q , 5 / 2 subtract from x = x - 5 / 2

now , multiply ( x - 5 / 2 ) by 4 = 4 ( x - 5 / 2 )

then, final result 3 times of original no.

=> 4 ( x - 5 / 2 ) = 3x

=> 4x - 10 = 3x

= > 4x - 3x = 10

=> x = 10

hence , the no. is 10
