​

Answer 1

Answer:

loss percent is 4%

hope i helped you.

thankyou

Answer 2

Step-by-step explanation:

SP 1st Transistors is Rs 600

Gain% = 20%

CP= 100/100+Gain%SP

CP=100/120*600

CP=Rs 500

SP of 2nd Transistor is rs600

Loss percent is 20 percent

CP=100/100-Loss%*SP

CP=100/80*600

CP=Rs 125

Total SP of both transistors is rs 600+rs600 = 1200rs

Total CP of the transistor is 125rs+500rs+625rs
