(A) Let the cost of Maruti and Figo a year ago be $3x$ and $4x$ respectively.Given the ratio of present to past year cost for Maruti is $5:4$,so present cost of Maruti $(PM)$ $= \frac{5}{4} 	imes 3x = 3.75x$.Given the ratio of present to past year cost for Figo is $3:2$,so present cost of Figo $(PF)$ $= \frac{3}{2} 	imes 4x = 6x$.The sum of their present costs is $7.8$ lacs:$3.75x + 6x = 7.8$$9.75x = 7.8$$x = \frac{7.8}{9.75} = 0.8$The cost of Figo a year ago was $4x = 4 	imes 0.8 = 3.2$ lacs.

$A$ year ago,the cost of Maruti and Figo were in the ratio of $3:4$. The ratio of present and past year costs of Maruti and Figo are $5:4$ and $3:2$,respectively. If the sum of their present costs is $7.8$ lacs,find the cost (in lacs) of Figo a year ago.
