Question

the difference between SI and cI on a certain sum for 2years at 5% per annum is rs26 find the sum​

Answer 1

Given :

• the difference between SI and cI on a certain sum for 2years at 5% per annum is rs26

To find :

• the sum

Solution :

p = (100/r)² × D

where r is rate and D is difference between SI and CI

= (100/5)² × 26

= 400 × 26

= 10400 Rs

Sum is 10400 Rs

Extra formula's :

• t_n = a + ( n - 1 ) d

• S_n = n/2 [ 2a + ( n - 1 ) d ]

• S_n = n/2 ( a + 1 )

Answer 2

Answer:

Question

the difference between SI and cI on a certain sum for 2years at 5% per annum is rs26 find the sum

To find

Sum

Formula applied

P = (100/r)² × D

Answer

➡️ P = (100/5²) × 26

➡️ P = (20)² × 26

➡️ P = 40 × 26

➡️ P = ₹10400

Sum = ₹10400
