Answer 2

Question:

What rate gives Rs 100 as interest on a sum of Rs 1000 in 2 years?

Answer:

⍟Formula used:

$Rᴀᴛᴇ = \frac{ɪɴᴛᴇʀᴇsᴛ*100}{Pʀɪɴᴄɪᴘᴀʟ*ᴛɪᴍᴇ}$

⍟Solution:

Interest= Rs.100

Principal= Rs.1000

Time= 2 years

$⇢ʀᴀᴛᴇ = \frac{ \cancel{100 }\times \cancel {100} \: \: ^{50} }{10 \cancel{00 }\times \cancel{ 2}}$

$⇢ʀᴀᴛᴇ = \frac{50}{10}$

$⇢ʀᴀᴛᴇ =5\%$

Therefore, The rate of the interest is 5%
