Question

Cost of 4 dozen bananas is Rs.180. How many bananas can be purchased for Rs. 90?

Answer 1

Cost of 4 dozen bananas = 60 RS.

Cost of 48 bananas = RS. 60 [4 dozen = 4 x 12 = 48]

∵ From Rs. 60, number of bananas can be purchased = 48

∴ From Rs.1, number of bananas can be purchased = $\frac{48}{60}$

= $\frac{4}{5}$

∴ From Rs. 12.50. number of bananas can be purchased = $\frac{4}{5}$×12.50

= $\frac{4}{5}$×12.50

= $\frac{4}{5}$×$\frac{1250}{100}$

= $\frac{250}{25}$

= 10 bananas

Thus, 10 bananas can be purchased for Rs.12.50.
