Question

If $2$ score strawberries can be bought for $Rs278.50$, what is the price of $1$ dozen strawberries?

Answer 1

We know

$1$dozen means $12$

$1$ score = $20$

Thus $2$ scores =$40$

Now $40$ strawberries cost $Rs278.5$

then cost of one strawberry is $Rs.6.9625$

So cost of $1$ dozen is $12\ast 6.9625=Rs.83.55$
