A boy was asked to multiply a number by 7/8, instead, he divided the number by 7/8 and got the result 15/14 more than what he should have got if he had multiplied the number by 7/8. The number is -
Let, the number be x
ATQ, 8x/7 - 7x/8 = 15/14
= > (64x - 49x)/56 = 15/14 = > 15x = 60 [ উভয়পক্ষকে 14 দ্বারা গুণ করে পাই ] = > x = 4
