Question

16 pens were divided among A, B and C in the ratio of 1 : 2 : 5. How many pens does B get?( 2 marks)

Answer 1

Let A have "$X$" pens,
then B has "$2X$" pens
and C has "$5X$" pens.
Pens with A + Pens with B + Pens with C =$X+2X+5X=16\Rightarrow 8X=16\Rightarrow X=2$
(1 mark)
So, A have $X=2$ pens,
B has $2X=4$ pens,
and C has $5X=10$ pens.
