1) Answer (E)

Parineeta’s present age = 33 – 9 = 24 yrs.
Manisha’s present age = 24 – 9 = 15yrs
Difference between Manisha and Deepali’s prresent ages = Parineeta’s present age
Deepali’s present age = Parineeta’s present age + Manisha’s present age = 24 + 15 = 39 yrs.
Ratio of the present age of Manisha and Deepali = 15 : 39 = 5 : 13
x = 13

2) Answer (E)

Total marks = 24 x 56 = 1344
Sum of actual marks = 1344 – (44 + 45 + 61) + (48 + 59 + 67) = 1368
Actual Average = $\frac{1368}{24}$ = 57

3) Answer (D)

Ritu’s marks = 56% of 875 = $\frac{56}{100}$ = 490

Smita’s marks = 92% of 875 = $\frac{92}{100}$ = 805

Rina’s marks = 634

Total marks = 1929

Average = $\frac{490 + 805 + 634}{3}$ = $\frac{1929}{3}$ = 643

4) Answer (E)

Share of A = $\frac{4}{11}$ x 73689 = 26796
Thrice share of A = 80388
Share of B = $\frac{7}{11}$ x 73689 = 46893
Twice the share of B = 93786
Difference = 13398

7) Answer (B)

Let x be the total number of students. 52% of the students participated i.e .52x students participated. 48% of the students did not participate i.e .48x students did not participate. Hence the ratio of students who did not participate to the students who participated is $\frac{.48x}{.52x}$ = $\frac{12}{13}$

8) Answer (C)

Let total number of members be T.The number of married number if percent is 28% = .28THence, percent of unmarried members = (100-28)%=72%And the number = .72TThe ratio of married to unmarried= .28/.72 = $\frac{7}{18}$

9) Answer (A)

Let numerator be x and denominator be y.If numerator is increased by 200% it becomes 3x and if numerator is increased by 150% it becomes 2.5yNow the new fraction is 9/10.Hence, (3x/2.5y)=(9/10) which gives $\frac{x}{y}$=$\frac{3}{4}$

10) Answer (C)

The time taken by her to type 5000 words essay at a speed of 60words/min = 5000/60=83.33

Time difference ~ 10 minutes

11) Answer (C)

Let the son age be x and fathers age be y. The solution is obtained by solving two simultaneous equations as per given conditions, x=y+10 and x+10=3(y+10) Hence, y = 5

12) Answer (B)

Let the number be x and another number be y.Now, the product of number and another number = x*yAs per given condition, new product (x/3)*1.5y=0.5xyNow, per cent of the product of the original numbers= (0.5xy/xy)*100=50
