Q.1 A car travelled 100km with half the distance at 40km/h and other half at 80km/h.Find the average speed.
Ans. 53.33km/h
|
S = V*T -> 50 = 40 * T -> t = 1.25 hours
S = V*T -> 50 = 80 * T -> t = 0.625 hours
Avg Speed = Total Distance / Total Time -> 100/(1.25+0.625) -> 53.33 Km/h

Q.2 At sale an article was reduced in price from rs. 180 to 171.If the article sold at the original price yielded 25% profit what will be the profit at reduced price
Ans. 18.75%
|
Selling article at 180 yields 25% profit
Cost Price = 180/1.25 -> 144
Selling at 171 means profit of(171 - 144) = 27
Calculating % -> 27/144 = 18.75%

Ans, 7366.70

600000 - 360000(60% advance) = 240000 (interest would be applied on this)
3.5% simple interest -> 240000*0.035 = 8400
240000 + 8400 = 248400 /36(3 years)
6900 per month
