Answer 1

A jar contained 370g of jam Usman ate 30% of the jam... What mass of jam remained in jar?

​Answer:

Amount of Jam in Jar before = 370g

Amount of Jam Usman ate = 30%

30% of 370g = $\frac{370}{100}$ × 30

                      = 3.7 × 30

                      = 111g

Amount of Jam Usman ate = 111g

Remaining amount of Jam in the Jar = Amount of Jam in Jar before - Amount of Jam Usman ate

= 370g - 111g

= 259g
