Question

Shan’s mother opened an oil packet of 1.50 L on Wednesday for cooking. Every day she uses 50 mL of the oil for cooking. After Sunday of the same week, find the amount of oil left in the packet.

• A. 1 L
• B. 100 mL
• C. 1250 mL
• D. 500 mL

Answer 1

The correct option is C 1250 mL

Shan’s mother opened the oil packet on Wednesday and has used it since that day.
She uses 50 mL of oil every day.

Initially, the oil in the packet was 1.50 L.
We know that, 1 L = 1000 mL
So, to convert the amount into mL = 1.50 × 1000 = 1500 mL
From Wednesday to Sunday, Shan’s mother has used 50 mL of oil every day.

Oil consumed = 5 × 50 mL = 250 mL

After Sunday, the remaining amount of oil in the packet is,
1500 – 250 = 1250 mL

Hence, the remaining amount of oil is 1250 mL.
