Rahul scored 12 marks more than Tanvi. If the ratio of the score of Tanvi to that of Rahul is 3 : 4, what is the sum of their scores ?
A). 82
B). 83
C). 84
D). 85
84
Let the score of rahul be R and that of Tanvi be T.
∴ According to the question,
R - T = 123 .................(1)
Also, T/R = 3/4
or, T = 3R/4
Putting the value of T in equations (1)
R - 3R/4 = 12=
R = 48, T = 36
Sum of R and T = 48 + 36 = 84
