Question

a man sold two typewriters it 2970 each. if he gain 10% on one in 10% loss on father what is his gain or loss percent​

Answer 1

original price of first typewriter = x  

2970/x = 110/100  

x = 2970 x 100/110 = 2700  

Price of first typewriter = Rs 2700  

Original price of second typewriter = y  

2970/y = 90/100  

y = 2970 x 100/90  

y = 3300  

Original price of second typewriter = 3300  

profit from first typewriter = 2970 - 2700 = 270  

Loss from second typewriter =  3300 - 2970= 330  

270 less than 330  

so he lost 330 - 270 = Rs 60 in whole transaction
