(a) 5 litres

(b) 7 litres

(c) 15 litres

(d) 12 litres

(e) None of these

Answer Posted / arpita saha

first case : in 10 lit
water content=(50/100)=.5 lit

second case
water content = (2% of x lit)

as the water content is same in both cases
thus
x=.5/.02
=> x= 25 lit

so,milk added=(25-10)=15 lit
