Answer 1

Answer:

24 of ₹ 5

40 of ₹ 2

and

50 of ₹ 1

Step-by-step explanation:

suppose we start with 20 coins of ₹ 2 because 20 is a multiple of 5 and 4

5 and 4 because these are the numbers in 3:5 and 4:5 corresponding to ₹ 2

so if we have ( 20 coins of ₹ 2

we have 12 of 5

and

25 of 1 rupee coins)

but adding values in this (bracket) we get ₹(5*12+2*20+1*25)

=₹( 60+40+25)

=₹ 125

Double it to get total ₹ 250

so we have

24, 40 and 50 coins of

5, 2 and 1 respectively.
