PSLE Gabby and Xuan each had a plate of dough of the same mass for making scones. The same mass of dough was used for each scone. Gabby made 33 scones and had 465 g of dough left. Xuan made 19 scones and had 1.095 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 Gabby and Xuan
= 33 - 19
= 14
1 kg = 1000 g
1.095 kg = 1.095 x 1000 = 1095 g
Difference between the remaining dough left by Xuan and Gabby
= 1095 - 465
= 630 g
Mass of 14 scones = 630 g
Mass of 1 scone
= 630 ÷ 14
= 45 g
(b)
Total remaining dough left
= 1095 + 465
= 1560 g
Sets of 45 g
= 1560 ÷ 45
= 34 r 30
Number of scones = 34
Answer(s): (a) 45 g; (b) 34
