PSLE Roshel and Emma each had a plate of dough of the same mass for making tarts. The same mass of dough was used for each tart. Roshel made 31 tarts and had 465 g of dough left. Emma made 11 tarts and had 1.165 kg of dough left.
- What was the mass of dough needed for each tart?
- With the remaining dough from both girls, how many more such tarts can be made at most?
(a)
Difference between the number of tarts made by Roshel and Emma
= 31 - 11
= 20
1 kg = 1000 g
1.165 kg = 1.165 x 1000 = 1165 g
Difference between the remaining dough left by Emma and Roshel
= 1165 - 465
= 700 g
Mass of 20 tarts = 700 g
Mass of 1 tart
= 700 ÷ 20
= 35 g
(b)
Total remaining dough left
= 1165 + 465
= 1630 g
Sets of 35 g
= 1630 ÷ 35
= 46 r 20
Number of tarts = 46
Answer(s): (a) 35 g; (b) 46
