Question

If 25 m of cloth costs Rs 337.50

a) What will be the cost of 40 m of the same type of cloth?

b) What will be length of the cloth bought for Rs 810 ?​

Answer 1

Answer:

a) 40 m of same type of cloth costs ₹540

b) For ₹810, cloth can be bought of the length = 60 m

Step-by-step explanation:

25 m of cloth costs ₹337.50

∴ 1 m of same type of cloth costs ₹$\frac{337.50}{25}$

∴ a) 40 m of same type of cloth costs ₹$\frac{337.50 x 40}{25}$ = ₹67.5 x 8 = ₹540

Again, for ₹337.50, cloth can be bought of the length 25 m

∴ for ₹1, cloth can be bought of the length $\frac{25}{337.50}$ m

∴ b) For ₹810, cloth can be bought of the length $\frac{25 x 810}{337.50}$ =$\frac{10 x 810}{135}$ = 60 m
