Correct question:-

The ages of reshma and rithika are in the ratio 3 : 4. 4 years before the ratio of their ages was 5 : 7. Find their present ages.

______________________________

Let Reshma's age be 3x and Ritika's age be 4x

Four Years Before the ratio of their age was 5:7

So,

Reshma's Age = 3x-4

Ritika's Age = 4x-4

A.T Q

 \frac{3x - 4}{4x - 4}  =  \frac{5}{7}  \\  \\ 7(3x - 4) = 5(4x - 4) \\ \\  21x - 28 = 20x - 20 \\  \\ 21x - 20x = 28 - 20 \\  \\ x = 8

•°• Present Age of Reshma = (3×8)= 24 years

•°• Present age of Ritika = (4×8) = 32 years
