Best answer
Correct Answer - a
(a) 4% = `(1)/(25)`, 3% = `(3)/(100)`
image
According to the question,
2500 units = Rs. 2000
1 unit = Rs. `(2000)/(2500)`
178 units = Rs. `(2000)/(2500)xx178`
= Rs. 142.40
Alternate
Principle = Rs. 2000 ,
Time = 2 years
`I^(st)` year Rate % = 4%
`II^(nd)` year Rate % = 3 %
image
Total CI = (80+60+2.4) = Rs. 142.40
