Answer 2

Answer:

By Unitary Method-:

Cost of 15 bananas = ₹24

Cost of one banana = ₹($\frac{24}{15}$)

Cost of 25 bananas = ₹($\frac{24}{15}$×25)

= ₹40

Hence, the cost of 25 bananas is ₹40

By Method of Proportion-:

Let us assume the cost of 25 bananas as ₹x

Then,

Ratio of bananas = Ratio of their costs

→ 15 : 25 :: 24 : x

Product of extremes = Product of means

→ 15 × x = 25 × 24

→ x = ($\frac{25 × 24}{15}$) = 40

Hence, the cost of 25 bananas is ₹40
