Divide Rs 6800 into two parts so that S.I. on the first part for 313 years at 6% may be equal to the interest on the second part for 312 years at 4% percent per annumOptionsRs 2600, Rs 4200Rs 2500, Rs 4300Rs 2700, Rs 4100Rs 2800, Rs

Let's denote the two parts as X and Y. We know that X + Y = 6800 (since the total amount is Rs 6800).

The problem states that the simple interest (SI) on the first part (X) for 3 1/3 years at 6% per annum is equal to the SI on the second part (Y) for 3 1/2 years at 4% per annum.

We can write this as:

(6/100) * X * (10/3) = (4/100) * Y * (7/2)

Solving this equation for X gives us:

X = (4/6) * (7/10) * (3/2) * Y

Substituting this into the first equation gives us:

(4/6) * (7/10) * (3/2) * Y + Y = 6800

Solving this equation for Y gives us:

Y = Rs 4200

Substituting Y = 4200 into the first equation gives us:

X + 4200 = 6800

Solving this equation for X gives us:

X = Rs 2600

So, the two parts are Rs 2600 and Rs 4200.
