Q. Salary of Arun is 1.5 lakhs. If salary of Arun is increased by 2k%, and then decreased by k%, and salary of Himanshi is increased by k%, after that both realized that net increment in salary of both (in Rs.) is same. Find the value of (3k + 167), if salary of Arun is 400% more than that of Himanshi.<\/p>\n\n\n\n
A.123<\/p>\n\n\n\n
B.234<\/p>\n\n\n\n
C.287<\/p>\n\n\n\n
D.250<\/p>\n\n\n\n
E. None of these<\/p>\n\n\n\n
Ans: <\/p>\n\n\n\n
Salary of Arun = Rs. 150000
Salary of Himanshi = Rs. 150000\/5 = Rs. 30000
Now,
30000 x k\/100 = 150000 x (2k \u2013 k \u2013 2k x k\/100) x
1\/100
1\/5 = 1 \u2013 k\/50
k\/50 = 4\/5
value of k = 40
required value = (3 x 40 + 167) = 287
Hence answer is option C<\/p>\n","protected":false},"excerpt":{"rendered":"
