Given: Cycle is decreased by 20% Then the selling is increased by 20%. Formula used: Loss% = (Loss × 100)/Cost price Calculation: Let earlier sale be Rs. x And earlier price be Rs. y The earlier revenue be Rs. xy According to the question: New price =Rs.y×(80/100) ⇒Rs.4y/5 New sale =Rs.x×(120/100) ⇒Rs.6x/5 New revenue =(4y/5)×(6x/5) ⇒24xy/25 Loss =(xy–24xy/25) ⇒(25xy–24xy)/25 ⇒xy/25 Loss% =(xy×100)/(25×xy) ⇒ 4% ∴ The impact on the receipt of the revenue is 4% loss.
