Question

with the money kanak has ,she can be either 3 pen or 50 pencils and she spends 80% of money and buy 10pens ao how many pencils she can buy with remaining amount

Answer 1

Answer:

Step-by-step explanation:

kanak can buy either 3 pen or 50 pencil, so cost of 3 pens are equal to cost of 50 pencils.

∴cost of 1 pen = $\frac{50}{3}$ ×cost of 1 pencil.

now kanak has spent 80% of money to buy 10 pens.

so she has now 20 % of money.

in 80%, she bought 10 pens so in 20% of remaining money she can buy $\frac{20\times 10}{80}$ = $\frac{20}{8}$pens

but 1 pen =  $\frac{50}{3}$ pencils.

∴total pencils she can buy in remaining amount = $\frac{20}{8}$× $\frac{50}{3}$.

=$\frac{125}{3}$
