If the numerator of a fraction is increased by 60% and denominator decreased by 20%, the new fraction is 5/8. Find the original fraction.
A. 3/8
B. 5/16
C. 5/12
D. 7/16
Answer: Option C
Solution (By JKSSB Mock Tests)
(1.6N)/(0.8D) = 2N/D = 5/8 → N/D = 5/16. Wait, 2N/D = 5/8 → N/D = 5/16. That's option B. So I'll set correct B. But I have options: 3/8, 5/16, 5/12, 7/16. So B. I'll adjust options: A 3/8, B 5/16, C 5/12, D 7/16. So answer B.
