SOS mum, actually the method works for this question too. Concept of ratio to find u. Only difference is previous question wants to find only one item, girls at first so multiply the u for the girls' part only but this question wants to find total items so multiply the u for total parts after u is solved.SOS mum wrote:Tks Sushi88

However, when i used the same concept for the following qn, it cldnt solve. Ps help. Tks and God Bless:)

The ratio of the number of muffins to the number of pies in a bakery was 4:1. After another 63 muffins and 46 pies were baked, the ratio became 3:1. How many muffins and pies were there in the bakery at first?

Before:

M:P

4u: u

After:

M: P

4u+63: u+46

3 : 1

(4u+63)/ (u+46) = 3/1

4u+63 = 3(u+46)

4u+63 = 3u+138

u = 138-63=75

**Hence total muffins and pies at first is 5u = 5 x 75 = 375**
