Answer / g.barathi
for 15 people = Rs.300
i.e 15*20 = 300
for 20 people = Rs.360
i.e 20*18 =360
increase in 5 people => Rs 60
for 1 = 60/5 =12
for 20 = 12* 20 = 240
so for 40 people = 360 + 240
= 600
one person has to pay =Rs. 15
i.e 600/40 = 15

Answer / hai
for 15---20---300
for 20---18---360
increase in 5 people discount is 40 (since 20*20=400
original amt but paid 360 i.e discount is 40)
for 40 people increase in people is 25 (40-15=25)
for 25 people disc is 25*40/5 =200
actual amt for 40 people is 40*20=600 deducting disc amt
paid by 40 people is 400
so each pays 10/-

Answer / anjali singla
If there are 15 people each has to pay Rs 20 , this means
total expenditure is Rs 300.
For 20 people total expenditure is Rs 360.
With increase in 5 person increase in expenditure is Rs 60 .
Therefore with increase of 20 person total expenditure
increase is Rs 240.
Hence total expenditure is Rs 400.
Total no of person is 40.
Amount to be paid by each person is Rs 12.50.
