Question

कोई धन 8 वर्षों में ₹660 और 12 वर्ष में ₹740 हो जाता है तो ब्याज की दर बताइए​

Answer 1

Step-by-step explanation:

Subtract the years - 12 - 8 = 4 yrs.

Subtract the Amounts - 740 - 660 = 80₹

Hence,

Interest for 4 years = 80₹

Hence,

Interest for 1 years = 20₹

Let's find the Rate of interest.

N = 8yrs.

I = 8×20 = 160₹

P = 660 - 160

= 500₹

R = ??

I = PRN / 100

160 = 500 × 8 × R / 100

R = 4%
