Question

Raju went to the stationery shop to buy some pens and pencils. He bought two times as many pens as pencils.He spent Rs 52 in all. If a pen costs Rs 12 and a pencil Rs 2, how many pens did he buy?

Answer 1

Answer:

Let no. of pencils ="X"

no. of pens. =2x

with respective to prices

the equation be like this

2x+12*2x=52

2x+24x=52

26x=52

'X'=2

2*X=2*2=4

therefore, no.of pencils=2

no.of pens =4
