Answer:

Rs 3200

Explanation:

The actual selling price was 20% below the cost price, so was ...

sp = cp(1 -20%) = 0.80cp

Had the selling price been raised, the selling price would have been 5% above the cost price:

sp +800 = cp(1 +5%) = 1.05cp

Subtracting the first equation from the second gives ...

(sp +800) -(sp) = (1.05cp) -(0.80cp)

800 = 0.25cp . . . . . . . simplify

3200 = cp . . . . . . . . multiply by 4

The cost price was Rs 3200.
