**A bottle of cooking oil weighs 2 kg. A hawker uses 8 such bottles in 4 days. If he uses the same amount of oil every day, how many 5-kg tins of cooking oil will he use in 10 days?****Solution**

1 bottle ----- 2 kg

8 bottles ----- 2 kg x 8 = 16 kg (for 4 days)

1 day ----- 16 kg divided by 4 = 4 kg (per day)

10 days ----- 4 kg x 10 = 40 kg

If 5-kg tins were used ----- 40 kg divided 5 kg = 8**Answer: He would use 8 5-kg tins in 10 days.****Note** – “The Singapore Hokkien Huay Kuan 5-School Combined Prelim Maths” is the common Maths Prelim Exam for Tao Nan, Ai Tong, Chongfu, Nan Chiau and Kong Hwa schools.
