Answer 2

Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Let the sum for 5% p.a. be 'x'

Let the sum for 7% p.a. be '4000-x'.

Number of years = 3 years

According to question, we get that

$\dfrac{x\times 5\times 3}{100}+\dfrac{(4000-x)\times 7\times 3}{100}=696\\\\\dfrac{15x}{100}+\dfrac{21(4000-x)}{100}=696\\\\15x+21(4000-x)=69600\\\\15x-21x+84000=69600\\\\-6x=69600-84000\\\\-6x=-14400\\\\x=\dfrac{14400}{6}\\\\x=2400$

So, at 7% p.a., we get that

$4000-2400=Rs.\ 1600$

Hence, Option 'c' is correct.
