Question

Raj is multiplying two numbers. By mistake, he read one of the numbers as 52 instead of
25 and as a result his answer increased by 486, What was the other number?

Answer 1

Answer:

18

Step-by-step explanation:

let the no. be x and the product be y

52 × x = y + 486        

52x - y = 486                     (1)

25x = y

25x-y=0                              (2)

by eleminating 1 and 2

we will get

x= 18

that is the other number is 18 and the correct product is 450
