PSLE Natalie and Jade each had a plate of dough of the same mass for making muffins. The same mass of dough was used for each muffin. Natalie made 35 muffins and had 275 g of dough left. Jade made 17 muffins and had 1.085 kg of dough left.
- What was the mass of dough needed for each muffin?
- With the remaining dough from both girls, how many more such muffins can be made at most?
(a)
Difference between the number of muffins made by Natalie and Jade
= 35 - 17
= 18
1 kg = 1000 g
1.085 kg = 1.085 x 1000 = 1085 g
Difference between the remaining dough left by Jade and Natalie
= 1085 - 275
= 810 g
Mass of 18 muffins = 810 g
Mass of 1 muffin
= 810 ÷ 18
= 45 g
(b)
Total remaining dough left
= 1085 + 275
= 1360 g
Sets of 45 g
= 1360 ÷ 45
= 30 r 10
Number of muffins = 30
Answer(s): (a) 45 g; (b) 30
