How did (6/7)² came some please explain
r= 14(2/7)%
= 100/7 %
= how!!!
I need answer without formula
There was a calculation mistake which is corrected now. Thanks for pointing it out.
how is it calculated?
Value of Maruti Van, V0= Rs. 196000
Rate of depreciation, r = 14(2/7)% = 100/7%; Time, t = 2 years
Let V1 is the value after depreciation.
V1 = V0*[1-(r/100)]t
V1 = 196000*[1-(100/7*100)]2
V1 = 196000*(6/7)2
V1 = (196000*36)/49 = Rs. 144000.
