Setoff

if it is a business activity u can setoff with other business income not with salary income

Yes, loss from letting out machinery can be set off against 'other income'  whether the said letting comprises loss from business income or 'other sources' . 

Agreed with Ms. Ruchi. The loss from leasing out or letting out of Plant and machinery can be set off against Income from business or income from other souces also, not particularly that the income comprises business income.However such loss cannot be allowed as deduction from certain incomes like winning from lotteries, races including horse races,card games and other games of any sort or form, gambling or betting of any form or nature as the sec 58(4) of the Income tax act do not allow any deduction from the incomes earned from the sources aforementioned.

So the answer for your question is YES, CAN BE SET OFF AGAINST INCOME FROM OTHER SOURCES ALSO

hope your doubt clears :-) 

IT IS NOT MENTIONED IN THE PROBLEM DAT IT IS A BUSI ACTIVITY OR NOT??
