	Dear Sanjeev 
	Take original cost of assest is Rs. 100
	Now 1st year dep on 100  @  30% will be 30 and net wdv will be (100-30)=Rs. 70
	in 2nd year dep charged on 70  @  30% will be 21 & net wdv (70-21) = Rs. 49
	in 3rd year dep charged on 49  @  30% will be 14.7 & net wdv (49-14.7) = Rs. 34.30
	in 4 th year dep charged on 34.3  @  30% will be 10.3 & net wdv (34.3-10.3) = Rs. 24
	anthor method
	Take calculator & start with 100
	Then press (-) 30% get 70, next (-) 30% get 49, next (-) 30% get 34.3, next (-) 30% get 24
