155

None of these

Option C
Ratio of work=1/15 : 1/24 = 8:5
Queen gets=(5/13)*390=150
A total of Rs 960 is been given to 3 persons X,Y and Z.X and Y can together complete 7/12 and Z and Y together can complete 5/12.So how much amount should be given to X?

280

350

300

None of these

Option B
X:Y=7:12
Z:Y=5:12
X:Y:Z=7:12:5

11 days

12 days

9 days

8 days

None of these

Option A
Priyanka:Queen=100:120
