Question

Sunita has 8 m cloth. She uses 2 m 5 cm cloth to make trousers and then she uses 3 m 8 cm to make shirts. What is the length of cloth left with Sunita?

• A. 2 m 8 cm
• B. 1 m 5 cm
• C. 5 m 13 cm
• D. 2 m 87 cm

Answer 1

The correct option is D 2 m 87 cm

We know that,
1 m = 100 cm

Length of cloth used to make trousers = 2 m 5 cm
= (2 × 100) cm + 5 cm
= 200 cm + 5 cm
= 205 cm

Length of cloth used to make shirts = 3 m 8 cm
= (3 × 100) cm + 8 cm
= 300 cm + 8 cm
= 308 cm

Total length of the cloth used to make trousers and shirts = 205 cm + 308 cm = 513 cm

Total length of cloth with Sunita = 8 m
= 8 × 100 cm
= 800 cm

Length of cloth left with Sunita = 800 cm - 513 cm
So, the length of cloth left with Sunita is 287 cm.

287 cm = 200 cm + 87 cm
= 2 m 87 cm

Thus, the length of cloth left with Sunita is 2 m 87 cm.
