. Two of them says that they have forgotten their purse so
remaining make an extra contribution of Rs 100 to pay up
the bill. Tell the no. of person in that group
Answer Posted / g.p
Total bill-2400..2 persons won't pay..we had a hint about group is more than 2 persons and each person share rs100 of 2 that persons to make 2400. Let's go for next... 2400 is divisible by 2,3,4,6,8,10&12. 2&3 can't be So on the group consists of 4,6,8,10&12 members.
4-2=2, 2400-200=2200, 2200/2=1100.when it is 4 members batch 2 pay 1100+100..it is unbalanced equation.when it is 6 members batch 6-2=4, 2400-400=2000, 2000/4=500 it is also a unbalanced. Let's go to 8 members batch 8-2=6, 2400-600=1800, 1800/6=300.when we adding 300+100=400 so 400*8=2400 Now it is balanced.So total batch member is 8.
