Question

by selling two transistors for rs. 600 each, a shopkeeper gains 20 percent on one transistor and loses 30 percent on the other . i) find the c.p of each transistor ii) total c.p and total s.p of both the transistor

Answer 1

Total loss=1357.14-1200=157.14
Loss%=157.14/1357.14 ×100
=11.58%

Answer 2

i.)for 1st transistor ,
CP=SP×100/100+P%
CP=600×100/100+20
CP=₹500
ii.)total SP=600+600=₹1200
totalCP=CPof 1 st transistor+CP of 2ndtransistor
totalCP=₹500+SP×100/100-L%}600×100/100-30
total CP=₹500+₹6000/7
totalCP=3500+6000/7(by taking l.c.m.)
totalCP=1357.14
