jagdish has three more rupees 5 coins than rupees 10 coins. If he has rupees 195 worth of money in total, how many of each coins does he have?
Answers
Answer:
15
Step-by-step explanation:
Total value of the sum = 10*x + 5(x+3)
which is equal to 195 as per question .
Number of Rs 5 note = 12 + 3 = 15
Step-by-step explanation:
let the number of 10 rupees coins = x
Therefore, number of 5 rupees coins = x + 3
Total money = 10(number of 10 rupees coins) +
5(number of 5 rupees coins)
= 10x + 5(x + 3)
= 10x + 5x +15
= 15x + 15
Therefore, according to the question
15x + 15 = 195
15(x + 1) = 195
x + 1 = 195 / 15
x + 1 = 13
x = 12
Therefore,
The number of 10 rupees coins = x = 12
Number of 5 rupees coins = x + 3
= 12 + 3
= 15
