Ratio of the age of Shreya to that of Bhoomika = \(\frac{15}{12}\)
\(= \frac{5}{4}\)
\(= 5:4\)
Thus, ₹ 36 divide between Shreya and Bhoomika in the ratio of \( 5 : 4.\)
Shreya gets = \(\frac{5}{9}\) of Rs 36
\(= \frac{5}{9} × 36\)
= Rs 20
Bhoomika gets =\( \frac{4}{9}\) of Rs 36
\(= \frac{4}{9} × 36\)
= Rs 16
Total money = ₹36
Shreya's age = 15 years
Bhoomika's age = 12 years
Sum of their ages \(= 15 + 12 = 27\)
Shreya's share of the money = \(\frac{15}{27} \times 36 = \frac{5}{9} \times 36 = 20\)
Bhoomika's share of the money = \(\frac{12}{27} \times 36 = \frac{4}{9} \times 36 = 16\)
Therefore, Shreya will get ₹20 and Bhoomika will get ₹16.
