Question

The ratio of ages of Prince and Arun is 3:4.
Prince is 5 years younger than Jayanthi.
The ratio of Arun’s age to that of Jayanthi’s age is 8:7.

What is Jayanthi’s age​

Answer 1

Answer:

THE JAYANTI AGE IS 35 YEAR

LET THE AGE OF PRINCE BE X AND ARUN BE Y AND JAYANTI BE Z

GIVEN

X/Y=3/4       Y/Z=8/7

AND      X+5  =Z

           X+5= 7Y/8

           X+5=7/8×4X/3

          X+5=28X/24

           28X=24X+120

           4X= 120

           X=120/4

            X=30

SO Y =  4X/3     =  4× 30/3      =   40 YEAR

AND Z =  7Y/8     =    7× 40/8     =35 YEAR
