Question

In how much years will the simple interest on a sum of money be equal to the principal at the rate of `16(2)/(3)` per annum(कितने वर्षो में वार्षिक की दर से किसी धनराशि का साधारण बियाज तथा मूलधन बराबर हो जायेगा )
A. 4years
B. 5years
C. 6years
D. 8years

Answer 1

(c ) `16(2)/(3)%=(1to"Interest")/(6to"Principle")`
Let principle=6 Interest=6
Let time=t years
By using the formula `(6)=(6xx50xxt)/(3xx100) Rightarrow t=6years`
`"Rate"%=16(2)/(3)=(1to"Interest")/(6to"Principle")`
Represents for 1years
According to the questions/. Principle=Interest 6=`1xx6`
Hence time=`1xx6=6years`
Alternate (तक)

Rate%`=16(2)/(3)%=(1 to "Interest)/(6 "to Principal")` ltbgt Represents for 1 years According to the question, Principal=interest=6=1xx6
Hence time=`1xx6=6`years
Note:If interest will be six times then time will also be six times:(यदि बियाज 6 गुना होता है तो समय भी छः गुना होगा)
