Question 12

Q12)Mohani has 30 m cloth and she wants to make some shirts for her son. If each shirt requires 2 m 30 cm cloth, how many shirts, in all, can be made and how much length of cloth will be left?

Solution :

Total length of cloth available = 30 x 100 = 3000 cm

Shirt made by using 2m 30cm (230cm) cloth = 1

Shirts made by using 30 m cloth

=\frac{1}{230}\times3000 = 13.04 = 13 shirts

Cloth required to make 13 shirts = 230 x 13 = 2990 or 29 m 90 cm

Hence, remaining cloth = 30 m - 29 m = 1m
