Question

Match the increases/decreases with their corresponding final values as per the following:

Initial value = ₹200

• A. ₹260
• B. ₹160
• C. ₹320

Answer 1

We know that final amount
= Initial amount $\pm$ Increase/Decrease

30% of ₹200 = Increase
$\Rightarrow$ $\frac{30}{100}\times 200$ = Increase
$\Rightarrow$ Increase = ₹60
$\therefore$ Final amount after 30% increase = ₹200 + ₹60 = ₹260

20% of ₹200 = Decrease
$\Rightarrow$ $\frac{20}{100}\times 200$ = Decrease
$\Rightarrow$ Decrease = ₹40
$\therefore$ Final amount after 20% decrease = ₹200 - ₹40 = ₹160

60% of ₹200 = Increase
$\Rightarrow$ $\frac{60}{100}\times 200$ = Increase
$\Rightarrow$ Increase = ₹120
$\therefore$ Final amount after 60% increase = ₹200 + ₹120 = ₹320
