70 coins of 10paise and 50paise are kept in a purse. If the total value of the money in the purse is ₹19. Find the number of each type of coins​

Answer 1

Your answer is 40 & 30

Step-by-step explanation:

Total coins 70

if, the numbers of 10 paise = a

and the numbers of 50 paise = b

a+b=70 =>b=(70-a)

total value of money is = (10×a)+(50×b) paise

according to the question Rs.19 = 1900paise

10a+50b=1900

=> 10a+50(70-a)=1900

=> 10a+3500-50a=1900

=> 40a=1600

=> a=40

and b=(70-40)=30

Number of 10 paise is 40

Number of 50 paise is 30
