Given : jab Kisi ladke se Kisi bhinn ka 6/7 batane ko kaha to usne 6/7se devide kr diya aur sahi answer se 13/70 adhik prapt hua
It was asked to get 6/7 of fraction but divided by 6/7 hence number obtained is 13/70 more than expected result
To Find : bhinn
Fraction
Solution:
bhinn = Fraction = A
bhinn ka 6/7 = 6A/7
usne 6/7se devide kr diya = A/(6/7) = 7A/6
7A/6 - 6A/7 = 13/70
multiplying both sides by 210
=> 7A * 35 - 6A * 30 = 13*3
=> 245A - 180A = 39
=> 65A = 39
=> A = 39/65
bhinn = 39/65
Fraction = 39/65
