i think 30 rupess ..but not surly

Answer 2

Answer:

a)10

Step-by-step explanation:

no of 20/- = x

no of 10/- = 3x

total money = 500

then ,

total = no of 20/- + no of 10/-

500 = x + 3x ( but here only we have wrote the no's of notes but not their value )

so, 500 = 20(x) + 10(3x)

500 = 20x+30x

500 = 50x

x = 500/50 => 10..

therefore , there are 10 , 20 rupees notes..;):)
