Question

Lata had ₹ 40000. She invested some amount in scheme A at CI at 15% and the remaining amount in scheme B at SI at 10%. If she got the same interest from both the investments at the end of one year. How much in ₹ did she invest in scheme B?

Answer 1

Answer:

24000

Step-by-step explanation:

Let the amount invested in Scheme A is ₹ x.

 

Then, the amount invested in Scheme B therefore will be ₹ (40000 – x)

 

We know that for the 1st year both Simple Interest and Compound Interest on a sum remains the same. Now, according to the question,  

 

⇒ 15% of x = 10% of (40000 – x)  

 

⇒ 15x = 400000 – 10x  

 

⇒ 25x = 400000

 

⇒ x = 16000  

 

∴  Amount invested in scheme B = 40000 – 16000 = 24000.
