Question

If a quarter kg of onion cost 40 rs., then cost of 200 gram onion will be _________.

Answer 1

Answer:

cost of 500 gm of onion= Rs 20.00 and cost of 1 kg of onion = Rs 40.00

Calculation:

1 kg = 4 x 1/4 kg

Given 1/4 kg of onions cost Rs 10.00

∴ Cost of 1 kg of onion = 4 x cost of 1/4 kg of onion = 4 x 10 Rs = Rs 40.00

We know that 1 kg = 1000 gm

∴ 500 gm = ( 1/1000) x 500 kg = (500/2x500) kg = 1/2 kg = 2 x 1/4 kg

∴ cost of 500 gm of onion = 2 x cost of 1/4 kg of onion = 2 x 10 Rs = Rs 20.00

Step-by-step explanation:

Answer 2

Answer:

As we know that,

1 quarter = 25%

1 quarter kilogram = 250 g

Cost of 250 g onion = Rs. 40

Cost of 1 g onion

= Rs. 40 ÷ 250

= Rs. 0.16

Cost of 1 g onion = Rs. 0.16

Cost of 200 g onion

= Rs. 0.16 × 200

= Rs. 32

Hence, Cost of 200 g onion is Rs. 32.
