Rahul obtained 12 marks more than that of tanvi If the ratio of their marks is 3 4 find the

x/(x+12) = 3/4
4x = 3x +36
x = 36
36+12= 48
sum of marks be 48+36 = 84

marks obtained by tanvi= x
marks obtained by rahul= x+12
ratio of there marks = 3/4
==> x/(x+12)= 3/4
==> 4x=3x+36
==> x= 36
so total marks obtained by rahul and tanvi = x+(x+12) = 36+36+12 = 84

4x-3x=12
x=12
mark of Rahul & tanvi = 36+48 = 84

tanvi's mark=x
rahul's mark=x+12
(x+12)/x=3/4
x=48
48+60=128
ans:128

let tanvi marks be x and so rahul marks become 12+x
also give rato=3:4=(12+x):x
so , 4x=36=3x
x=36 and rahul marks=48 their sum=84
