Answer / vignesh1988i

may be this would be right....

let the tube cost be : x
carburetor cost is : 1/3 x
braking charge is : 2/3 x
cost of acc is : 1/3 x
cost of wheel balance is : 1/3 x

given that total cost repair is 195...
so it includes all the above cost.
so ,
x + 1/3x + 2/3x + 1/3x + 1/3x =195
solving we get x= Rs.73.12

so tube cost is Rs. 73.12

Answer / swetanjli

let cost of tube= x
so,the cost for carburator = 1/3 x
the cost for breaking = 2/3 x
the cost for acc = 1/3 x
the cost for wheel balancing = 1/3 x
and the total cost = 195
thus
x + 1/3 x + 2/3 x + 1/3 x + 1/3 x = 195
L.H.S= 8x/3 = 195
195 * 3/8 = 72.9
thus the cost of tube repair is 72.9
