A wholesaler allows a discount of 25 % on the list price to the retailer. The retailer sells at 5% below the list price. If the customer pays Rs.38 for an article what profit is made by the retailer on it?
If wholesaler's list price=100%, Retailer's CP=75% & SP=95%
If SP of 95% of the retailer costs Rs.38 to customer,so its CP of 75% will cost 75*38/95= 30
Profit is made by the retailer= 38 - 30 = 8
Pappu and Gappu are 180 km apart they start to move towards each other simultaneously, Pappu at speed 20 km/hr and Gappu at 10 km/hr if every hour they double their speed what is distance that Pappu will travel until he meets Gappu
In 2 hours Pappu covers (20+40) = 60 km
Gappu covers( 10 + 20) = 30 km,
Total covered = 90
In the next hour they have to cover (180 - 90) kms with the speeds 80km/hr and 40 km/hr respectively.
Let them take another t hrs to meet
so sum of the distance to be covered by both is 90 km
(80*t) + (40*t) = 90km
=> t= (3/4) hrs
we need to find out the distance covered by Pappu
which equals to = 60 + (80*(3/4)) = 120 km
