Step-by-step explanation:
C.P. of one almirah =Rs.4800
Gain%=13 1/3 %= 40/%
∴S.P.= C.P.×(100+Gain%)/100
= 4800×(100+ 40/3) /100
= 4800×340/100x 3
=Rs.5440
C.P. of second almirah =Rs.3640
Loss%=15%
S.P.= C.P.×(100−Loss%)/100
=
100
3640×(100−15)
=Rs.
100
3640×85
=Rs.3094
C.P. of both the almirahs =Rs.4800+Rs.3640=Rs.8440
and S.P. =Rs.5440+Rs.3094=Rs.8534
Total gain = S.P. - C.P. =Rs.8534−Rs.8440=Rs.94
