a purse contains rupees₹ 10 rupees 5 and rupees2 to by number in the ratio 2 ratio 5 ratio 7 and the total value of all the coins is rupees 236 find the number of each type of coins
Answers
Answer:
Let the number of 1, 2 and 5 rupee coins be 2y, 4y and 5y
Total value of 1 rupee coin = value of one coin x number of coins
= Rs 1 x 2y
= Rs 2y
Similarly, total value of 2 rupee coin = Rs 2 x 4y =Rs 8y
And total value of 5 rupee coin = Rs 5 x 5y = Rs 25y
Total values of all coins put together = Rs (2y + 8y + 25y)
= Rs 35y
According to question, Total value = Rs 455
Hence, 35y = 455
⇒ y = 455/35 = 13
Thus, number of 2 rupee coin = 4y = 4 x 13 = 52
CHECK:
Number of 2 rupee coin = 52
Number of 1 rupee coin = 2y = 26
Number of 5 rupee coin = 5y = 65
Value of 2 rupee, 1 rupee and 5 rupee coin would be Rs 104, Rs 26 and Rs 325 respectively
Total value = Rs ( 104 + 26 = 325) = Rs 455
