PSLE Yen and Jade each had a plate of dough of the same mass for making scones. The same mass of dough was used for each scone. Yen made 37 scones and had 335 g of dough left. Jade made 19 scones and had 1.145 kg of dough left.
- What was the mass of dough needed for each scone?
- With the remaining dough from both girls, how many more such scones can be made at most?
(a)
Difference between the number of scones made by Yen and Jade
= 37 - 19
= 18
1 kg = 1000 g
1.145 kg = 1.145 x 1000 = 1145 g
Difference between the remaining dough left by Jade and Yen
= 1145 - 335
= 810 g
Mass of 18 scones = 810 g
Mass of 1 scone
= 810 ÷ 18
= 45 g
(b)
Total remaining dough left
= 1145 + 335
= 1480 g
Sets of 45 g
= 1480 ÷ 45
= 32 r 40
Number of scones = 32
Answer(s): (a) 45 g; (b) 32
