Answer 1

first decreased by 25%

Further decrease by 40%

total degrees is equal to 75%

therefore,

$100 \times \frac{75}{100} = 75 \: percent$

Answer 2

Answer:

55%

Step-by-step explanation:

let the original cost be - rs 100

decreased by 25%

therefore,

new cost= 100-25 = rs 75

decreased by 40%

=75×100/100= rs 30

therefore,

new cost = rs 75-30= rs 55

= 55/100 × 100 = 55

ans = 55% decreased
