Question

If the cost of 4 dozen bananas is rs 104. How many bananas can be purchased for rs 6.50

Answer 1

Cost of 4 dozen bananas= Rs.104
4dozen= 4×12=48 bananas

How many bananas can be purchased for Rs.6.50=?

[Product of mean = Product of extreme]

Therefore,

48:x::104:6.50
=> 48×6.50=104×x
=> 312= 104x
=> 312/104= x
=> 3= x

Hence,
3 bananas can be purchased for Rs.6.50
