Original number = 100 (given)

Find the number after it is increased by 40%:

40% increased = 40% x 100 = 0.4 x 100 = 40

Number after increased = 100 + 40 = 140

Find the number after it is increased again by 40%:

40% increased = 40% x 140 = 0.4 x 140 = 56

Number after increased = 140 + 56 = 196

Answer: The final number is 196

Original number = 100 (given)

Find the number after it is increased by 40%:

40% increased = 40% x 100 = 0.4 x 100 = 40

Number after increased = 100 + 40 = 140

Find the number after it is decreased by 40%:

40% decreased = 40% x 140 = 0.4 x 140 = 56

Number after decreased = 140 - 56 = 84

Answer: The final number is 84

siri542: but how

TooFree: It started with 100 .. and both times it increased .. how can that be?

TooFree: Could one of them is meant to be written as decreased?

siri542: but the answer is 84

TooFree: I figured it out .. the question is supposed to be increased by 40% and then decreased by 40% .. you did not write the question right.

dpsdurgstudent: then your question might be first increased and then decreased

siri542: yes

TooFree: I wrote your question and the answer into my answer. Check the work if you need the details.

dpsdurgstudent: Check my answer

$= 100 \times \frac{(100 + 40)}{100} \times \frac{(100 - 40)}{100} \\ = 100 \times \frac{140}{100} \times \frac{60}{100} \\ = 14 \times 6 \\ = 84$
