Answer 1

Step-by-step explanation:

14.))) 2x+3x+5x= 400000

10x= 400000

x=400000/10= 40000

so the100rs

the 50rs as= 3x= 3×40000=120000

the 10rs as=5x= 5×40000=200000

so,

number of 100rs are =80000/100=800

number of 100rs are =80000/100=800number of 50rs are=120000/50=2400

number of 100rs are =80000/100=800number of 50rs are=120000/50=2400number of 10rs are= 200000/10= 20000
