Answer 1

Answer:

8%

Step-by-step explanation:

The share expenditure on milk is 40% of the total

expenditure of the family. The cost on it increased by

20%, then the % of new expenditure on milk is what %

of new total expenditure of family/

(a) 18% (b) 8% (c) 16.66% (d) 15%​

Let say Total Expenditure = 100E

then Expenditure on Milk = (40/100)100E = 40E

Cost of milk increased by 20 %

= (20/100) * 40E = 8E

New Cost = 40E + 8E = 48E

New added expenditure = 8E

in % =  (8E/100E) * 100 = 8 %

% of new expenditure on milk = 8%
