If in 2003, the fees of primary section was Rs. 420 and that of secondary section was Rs. 630, then in which year primary section will have Rs. 40 more fees than the secondary section? Correct Answer 2028
Given:
The fees of primary section (X) increases by Rs. 40 every year,
while the fees of secondary section (Y) increases by Rs. 30 every year
Calculation:
Suppose primary section will have Rs. 40 more fees than the secondary section after z years.
Then, (420 + 40z) - (630 + 30z) = 40
⇒ 10z – 210 = 40
⇒ 10z = 250
⇒ Z = 25
∴ Primary section will have Rs. 40 more fees than the secondary section after 25 years i.e. 2028
