Question

if one chalk costs rs 0.30 how many chalk can be bought with rs 15 ?​

Answer 1

Answer:

Step-by-step explanation:

Product of means = Product of extremes

1 : 0.30 = x : 15

where, x's value is unknown

o.30 x = 15

x = 15 / 0.30 = 15/0.30 the whole multiplied by 100 - to remove the point.

x = 1500/30 = 50 chalks.
