Question
₹ 6,900 is divided between L, M and N in the ratio of
6: 8: 9. If 'L' and 'M' each gave ₹ 300 to N then the new ratio of shares of L, M and N is:Solution
Solution-Total of L M N =6900 Ratio of L M N=6: 8: 9 ATQ- 23=6900 1=300 L M N 1800 2400 2700 'L' and 'M' each gave ₹ 300 to N= L M N 1500 2100 2700+300+300=3300 15 21 33 So, the new ratio of L M N=5:7:11.
