Question

Rs 200 amounted to Rs 280 in 4 years at
a certain rate. If the rate is increased by
1%, the amount would be
(a) Rs 284 (b) Rs 300 (c) Rs 288​

Answer 1

Answer:

it's actually 282 but I would say 284

Step-by-step explanation:

280 + (1% × 280) =

280 + 1% × 280 =

(1 + 1%) × 280 =

(100% + 1%) × 280 =

101% × 280 =

101 ÷ 100 × 280 =

101 × 280 ÷ 100 =

28,280 ÷ 100 =

282.8
