Answer : Option B
Explanation :
C.P. of 1st transistor = Rs. | ![]() |
\(\frac { 100 } { 120 }\)x 840 | ![]() |
= Rs. 700. | |
C.P. of 2nd transistor = Rs. | ![]() |
\(\frac { 100 } { 96 }\)x 960 | ![]() |
= Rs. 1000 | |
So, total C.P. = Rs. (700 + 1000) = Rs. 1700.
Total S.P. = Rs. (840 + 960) = Rs. 1800.
