c) 13970

d) 15702

e) None of these

a)

Number of children in 1989

Total population in 1989 – Total Population of men and women

160998-148585 = 12413

D.6-10) 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.

6) Total how many boys went to only physics lab ?

a) 175

b) 158

c)156

d)134

e) None of these

b)

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

7) How many girls went to only physics lab ?

a) 62

b) 46

c) 64

d) 60

e) None of these

c)

No of girls (phy) = (280-126 – 90) = 64

8) 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 these

b)

Total no of students went to only phy = 128+64 = 192

% = 192*100/600 = 32%

9)  What is the total number of girls went to chemistry lab ?

a) 216

b) 210

c) 267

d) 261

e) None of these

a)

Total no of Girls(chem) = 126+90 = 216

10) What is the total number of students went to only chemistry lab ?

a) 244

b) 248

c) 284
