Hi Archit3110
750 is given only for Yes to R and No to S , not both R and S
you are including both R and S in 750

At a local election there were two propositions on the ballot, R and S. Twice as many voters voted "yes" for R as for S. If the number who voted "yes" for R but "no" for S was 750 and the number who voted "yes" for S but "no" for R was 310, how many voted "yes" for both propositions?

A. 122
B. 127
C. 130
D. 135
E. 140


Since given that yes of R = 2* yes of S

So 310 Yes of S = 310* 2= 620 Yes of R
And for both 750-620 = 130 option C


sunita123 solution attached 2x2 matrix..

R S
I. Y1 Y1 = we have to find out ??
II. N2 N2
IIII. Y3 N3. = 750 given
IV. N4 Y4. = 310 given

As per question

2(Y1+Y4)=(Y1+Y3)
2(Y1+310)=(Y1+750)

Y1 = 130
This implies 130 people voted yes for both R&S
