Quantitative Aptitude ( CCS) Data Table

NA refers the data which is not needed for a particular question. The number of working days of A, B, C, D is given below and some of them are missing. Take the data of the first row for the first question and the second row for the second question and so on.

A	B	C	D	Ratio	Total Number of Working Days
_	25	NA	NA	Efficiency (A : B) = 5 : 4	NA

Working together B and C take 50% more number of days than A, B and C together take and A and B working together, take 8/3 more number of days than A, B and C take together. If A, B and C all have worked together till the completion of the work and B has received Rs.120 out of total earnings of Rs. 480 then in how many days did A, B and C together complete the whole work?

Explanation:

Explanation :
The days ratio of (A + B + C) : (B + C) = X:3X/2 = 2X:3x;
Efficiency ratio = 3X:2X
Efficiency of A = x.
(480/3X) = Rs.160
Amount received by B = Rs.120 & C = 200
160:120:200 =4:3:5
1/4:1/3:1/5= 15:20:12;
(1/15+1/12+1/20)*Y = 1
Y = 5 days
