A man bought a piece of land for ₹48,000. He sold two-fifth of it at a loss of 10%. At what gain percentage (rounded off to 1 decimal place) should he sell the remaining land to earn an overall profit of 42%?
Answer & explanation
Correct answer: option 1
Let the total quantity = 10
CP SP
Two fifth 4 3.6
three fifth 6 x
—————————————
10 14.2 (overall gain = 42%)
x = 14.2 - 3.6 = 10.6
Profit at which remaining is sold = ( 10.6 - 6) × \(\frac{100}{6}\) = 76.7%
