Answer 2

$\huge\mathfrak{Answer:}$

Given:

• We have been given that the ages of Rani and Romi are in the ratio of 5:7.
• Sum of their ages after 4 years is 56.

To Find:

• We need to find their present ages.

Solution:

As we have been given the ratio of their ages as 5:7 so, let us assume their ages to be 5x and7x.

After four years,

Rani's Age = 5x + 4

Romi's Age = 7x + 4

According to the question, we have

$\sf{5x + 4 + 7x + 4= 56}$

$\implies \sf{12x + 8 = 56}$

$\implies \sf{12x = 56 - 8}$

$\implies \sf{12x = 48}$

$\implies \sf{x = \dfrac{48}{12} }$

$\implies \sf{x = 4}$

Rani's Age = 5x = 5 × 4 = 20 years

Romi's Age = 7x = 7 × 4 = 28 years

Hence, the present age of Rani and Romi is 20 and 28 years respectively.
