How much cloth will be used in making 6 shirts, if each required `2 1/4` m of cloth, allowing `1/8` m for waste in cutting and finishing in each shirt?
योग
उत्तर
Cloth is required in making one shirt
= `(2 1/4 + 1/8)`
= `((2 xx 4) + 1)/4 + 1/8`
= `9/4 + 1/8`
= `(18 + 1)/8` .....[∵ LCM of 4 and 8 = 8]
= `19/8` m
∴ Total cloth required in making such 6 shirts = 6 × Cloth required in one shirt
= `19/8 xx 6`
= `(19 xx 3)/4`
= `57/4`
= `14 1/4` m
Hence, `14 1/4` m cloth will be used in making 6 shirts.
