of r?
कोई धनराशि r% साधारण ब्याज की दर पर 35 वर्षों में स्वयं का
79/16 गुना हो जाता है, तो r का मान क्या होगा?​

Answer 1

Answer:

r=11.25%

Step-by-step explanation:

SI=P×R×T/100

Given:-

Amount=(79/16)×P

SI=Amount-Principal

SI=(79/16)P-P

=((79-16)/16)P

=63P/16

Therefore,

63P/16=P×R×T/100

35r=6300/16

r=(6300/16)/35

=6300/(16×35)

=6300/560

=11.25%
