Homework answer 1) selling price= 1120 discount percent= 20 marked price = x WKT 20%+x%=100% x%= 100-20=80% So, value of marked price= 80/100*x = 0.8 1120(SP)= 80/100*x = 1120/0.8 (*100) (*100) = 1120/8= 1400 Hence, the marked price of the jacket is Rs1400. 2) So, we can take it in the form of compound interest. principal= 20,000 rate of interest= 25% time period= 2years Amount= p(1+R/100)^2 20,000(1+25/100)^2 20,000*5/5*5/4 =1250*25= 31,250 The population of the city after two years will be 31,250 Thanks!

Mam the answer for 1st question is:- Let the mp be x so, Disount / 100 * x = 1120 20/100* x =1120 X = 1120 *5 5600 So, the marked price is ₹5600 2nd question :- Population of city after 2 years =A=20000[1+25/100 ] to the power 2 A =20000[4/4 +1/4] to the power of 2 A= 20000*5/4*5/4 A = 31250 So ,the population after 2 years is 31,250. By radhika sharma

[@Manas-zv6hy]

First Year: Population increase = 20,000 * 25% = 20,000 * 0.25 = 5,000 Population after the first year = 20,000 + 5,000 = 25,000 Second Year: Population increase = 25,000 * 25% = 25,000 * 0.25 = 6,250 Population after the second year = 25,000 + 6,250 = 31,250 So, using the simple percent method, the population of the city after 2 years will also be 31,250.

[@ishwarishinde4133]

Answer for homework question: Let the marked price of the jacket be Rs x Discount % on marked price = 20% Selling price of jacket = Rs 1120 Then, 1120 = x − x × 20 100 ⇒ 1120 = x − x 5 ⇒ 1120 = 4 x 5 ⇒ x = 1120 × 5 4 = 280 × 5 = R s 1400 So, marked price of the jacket is Rs 1400.

[@soumyauhhh]

SP of the jacket= ₹1120 Discount%= 20% MP= 1120 × 100 / 80 = ₹1400
