I.Study the information carefully to answer the given questions
In a college out of 600 students, boys and girls are in the ratio 8: 7. Each students went to either physics lab or chemical lab or both, 40% of the boys attend only physics lab, total 20% children went to both the labs out of which 25% are boys, 45% of the girls went to only chemistry lab.
- Total how many boys went to only physics lab ?
A)175
B)158
C)156
D)134
E)None of theseB)158
Explanation :
8:7 = 320(boys):280(girls)
20% both = 20*600/100 = 120
B – (phy ) = 40*320/100 = 128
B – (both) = 25*120/100 = 30
G – (chem) = 45*280/100 = 126
Total no of boys(phy) = 128+30 = 158 - How many girls went to only physics lab ?
A)62
B)46
C)64
D)60
E) None of theseC) 64
Explanation :No of girls (phy) = (280-126 – 90) = 64 - Total number of students went to physics lab is what percentage of the total number of students in the college
A)22%
B)32%
C)33%
D)36%
E) None of theseB)32%
Explanation :
Total no of students went to only phy = 128+64 = 192
% = 192*100/600 = 32% - What is the total number of girls went to chemistry lab ?
A)216
B)210
C)267
D)261
E) None of theseA)216
Explanation :Total no of Girls(chem) = 126+90 = 216 - What is the total number of students went to only chemistry lab ?
A)244
B)248
C)284
D)288
E) None of theseD)288
Explanation :Total no of students(chem) = (320-128-30)B + 126G = 162 + 126 = 288
8:7 = 320(boys):280(girls)II. Study the information carefully to answer the given questions
