A table is marked (z+5)% above its cost price and a

Solution

If the cost price of the table is Rs.1485 more than its selling price.

Let’s assume the cost price of the table is Rs. ‘y’.

selling price of the table = Rs. (y-1485)

A table is marked (z+5)% above its cost price and a discount of 35% was given on it while selling  and the MRP of the table is Rs. 23100.

y of (100+z+5)% = 23100    Eq.(i)

y of (100+z+5)% of (100-35)% = (y-1485)    Eq.(ii)

Put Eq.(i) in Eq.(ii).

23100 of (100-35)% = (y-1485)

23100 of 65% = (y-1485)

15015 = (y-1485)

y = 15015+1485 = 16500

Put the value of ‘y’ in Eq.(ii).

16500 of (100+z+5)% of (100-35)% = (16500-1485)

16500 of (105+z)% of 65% = 15015

165x(105+z)x65 = 1501500

(105+z) = 140

z = 140-105

Value of ‘z’ = 35
