(A) 6.66%

(B) 8.33%

(C) 9%

(D) 7.5%

Answer key:
1. Sol. (C) 

R = [{(1620 – 1350) × 100}/ {(1350 × 8 – 1620 × 5)}] = 10%
P = (270 × 100)/ (10 × 3) = Rs. / рд░ू. 900

2. Sol. (C)
Let number of ladies who did not report for the work be x. / рдоाрдиा рдорд╣िрд▓ाрдУं рдХी рд╕ंрдЦ्рдпा рдЬो рдХाрдо рдкрд░ рдирд╣ीं рдЖ рд╕рдХीं, x рд╣ै ।
(76 – x) × 44 = 76 × 33
44x = 76 × 44 – 76 × 33
x = (76 × 11)/ 44
x = 19

3. Sol. (D)
Let fourth proportional be x. / рдоाрдиा рдЪौрдеा рд╕рдоाрдиुрдкाрддिрдХ x рд╣ै ।
7: 11 :: 14: x
7 × x = 11 × 14
x = 22

4. Sol. (B)

B alone can do the work in/ B рдЕрдХेрд▓ा рдХाрд░्рдп рдХो рдХрд░ рд╕рдХрддा рд╣ै = 1/ {(1/12) – (1/20)}
= 1/ {(5 – 3)/ 60} = 1/ (2/60)
= 30 days/ рджिрди
B's one day work/ B рдХा рдПрдХ рджिрди рдХा рдХाрд░्рдп = 1/30
B's half day work/ B рдХा рдЖрдзे рджिрди рдХा рдХाрд░्рдп = 1/60
According to question/ рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
Time taken by A and B/ A рдФрд░ B рдж्рд╡ाрд░ा рд▓िрдпा рдЧрдпा рд╕рдордп = 1/ {(1/20) + (1/60)}
= 1/ {(3 + 1)/ 60} = 1/ (1/15)
= 15 days/ рджिрди

5. Sol. (B)

C.P. / рдХ्рд░рдп рдоूрд▓्рдп S.P. / рд╡िрдХ्рд░рдп рдоूрд▓्рдп Profit/ рд▓ाрдн
100 115 15%
95 104.5 10%
10.5 = 21
1 = 2
100 = 200

6. Sol. (B)
{54.6/ (x + 15 + x)} = 2 + (3/5)
{54.6/ (2x + 15)} = 13/5
273 = 26x + 195
26x = 78
x = 3

7. Sol. (A)
Let/ рдоाрдиा Q = x
P = x + 7
R = x – 6
According to the question/ рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
x + x + 7 + x – 6 = 76
3x + 1 = 76
3x = 75
x = 25
Required ratio/ рдЕрднीрд╖्рдЯ рдЕрдиुрдкाрдд = 32: 25: 19

8. Sol. (A)

P = 76.25 × (100/5)2 × (100/305)
= Rs. / рд░ु. 10000

9. Sol. (B)
960 × 30 × h = 40 × 30 × 12
h = 0.5 m. / рдоी.



10. Sol. (B)

Let C.P. for Anushika/ рдоाрдиा рдЕрдиुрд╖िрдХा рдХे рд▓िрдП рдХ्рд░рдп рдоूрд▓्рдп = 100%
M.P. for Anushika/ рдЕрдиुрд╖िрдХा рдХे рд▓िрдП рдЕंрдХिрдд рдоूрд▓्рдп = 150%
S.P. for Anushika/ рдЕрдиुрд╖िрдХा рдХे рд▓िрдП рд╡िрдХ्рд░рдп рдоूрд▓्рдп = 120%
C.P. for Aastha/ рдЖрд╕्рдеा рдХे рд▓िрдП рдХ्рд░рдп рдоूрд▓्рдп = 120%
S.P. for Aastha/ рдЖрд╕्рдеा рдХे рд▓िрдП рд╡िрдХ्рд░рдп рдоूрд▓्рдп = 120% + 20
According to the question/ рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
120% + 20 = 130%
10% = 20
120% = 240
Required Profit/ рдЕрднीрд╖्рдЯ рд▓ाрдн % = (20/240) × 100 = 8.33%
