We have to spend rs 100 by purchasing 100 items using the condition

Question

We have to spend RS 100 and buy 100 items according to given condition
1 peacok RS 15
1 pezions RS 1
20 sporrow RS 1

Answer 1

if all three types have to be bought there is no solution because
if a= number of peacocks
b= number of pigeons
c=number of sparrows , these conditions for quantity and cost respectively must satisfy
a+b+c=100
15a+b+c/20=100
subtract 14a=19c/20 or a=19c/280
for a to be a whole number c has to be 280 which violates the fundamental condition of a,b,c each <100
