Usha bought some eggs to bake cakes for a party. If she used 6 eggs for each cake, she would be short of 19 more eggs to bake all cakes. If she used 11 eggs for each cake, she would be short of 64 more eggs.
- How many cakes did she bake?
- How many eggs did Usha buy?
(a)
Small difference
= 11 - 6
= 5
Big difference
= 64 - 19
= 45
Number of cakes that Usha bought
= 45 ÷ 5
= 9
(b)
Number of eggs that Usha bought
= 9 x 6 - 19
= 54 - 19
= 35
Answer(s): (a) 9; (b) 35
