D’s can do peace of work=80 day’ s

M:F=4:1

E’s can do peace of work=100 day’ s

M:F=1:4

According to question,

Men can do alone in D=80×5/4=100 day’s

Woman can do alone in E=100×5/4=120 day’s

Require answer, (Efficiency of D and E)

D/E=((1/100))/(1/120) =>D/E=120/100=6/5

Wage of women from city E,

9500×5/11=4318.18~ 4318

d

B’s three day’s work=3×1/42=1/14; Remaining work=1-1/14=13/14.

(A+B)’s one day’s work=1/21+1/42=3/42=1/14.

13/14 work in finished by (A+B) in (13/14×14/1) days=13 days.

Total number of days=3+13=16 days.

16 days.

b)

According to question,

Ratio of wages of D,E,F=(80×5) :(100×6) :(120×4)=400 :600 :480=10 :15 :12

F’s share=(13172 ×12/37)=Rs. 4272

Required answer,

Men in E’s share=(4272×3/4)=Rs. 1181.75~1182

5) A and B work together for 6 days and the rest of the work is done by C in 2 days. If they get Rs.4200 for the whole work, How much amount will be received by Women in C?

a)

(A+B)’ s six day’s work=6(1/21+1/42)=6(3/42)=6/14=3/7

Remaining work=1-3/7=4/7.

C’ s two days work=4/7

=(A’s six days’ work) :(B’ s six days’ work) :(C’ s two day s work)

=6/21 :6/42 :4/7=2/7 :1/7 :4/7 =>2 :1 :4

C’s share=(4200×4/7)=Rs. 2400

Required Answer, (Women in C)

=2400×3/10=Rs.720

D.6-10) Study the following information carefully and answer the questions given below:Total monthly amount of principal = Rs.10,000

 

6) What is the difference between the difference of simple and compound interest to Q and the difference of simple and compound interest to P in given years?

a) Rs.250.64

b) Rs.350.64

c) Rs.450.64

d) Rs.550.64

e) None of these

b)

Sum of principal amount P per annum=10000×27/100×12=32400

Sum of principal amount Q per annum=10000×15/100×12=18000

According to question,

The difference of simple and compound interest to P=32400(8/100)^2=207.36

The difference of simple and compound interest to Q=18000 (10/100)^2 ((300+10)/100)=558

Required answer,

Q-P=558-207.36=350.64

7) Find compound interest for 6 months compounded quarterly in T?

a) Rs.2569.76

b) Rs.2669.76

c)Rs.2769.76

d) Rs.2869.76

e) None of these

Click Here to View Answer
b)

Principle amount of T per annum=10000×18/100×12=21600

R=6% per half-year, t=2 half-years

Amount={21600(1+6/100)^2 }=21600×53/50×53/50=24269.76

CI=(24269.76-21600)=Rs. 2669.76

8) What is the total amount to T in given years? (using Simple interest)

a) Rs.28240

b) Rs.29240

c) Rs.31968

d) Rs.31240

e) None of these

c)

According to question,

Toal amount of T=21600 (1+(4×12)/100)=31968

9) What is the respective ratio of the total amount of U to the total amount of V with using compound interest? (Approximately)

a) 422 : 625

b) 950 : 625

c) 820 : 387

d) 625 : 950

e) None of these

Click Here to View Answer
d)

According to question,

The total amount of U,

Principal=10000×8/100×12=9600

U=9600((1+25/100)^2 )=Rs.15000

The total amount of V,

principle=10000×11/100×12=13200

V=13200((1+20/100)^3 )=22809.6

Required answer,

U :V=15000 :22809.6

U :V=625 :950.4 ~ 625 :950

10) What is the average of the total amount of P, Q, R and S using simple interest in given years?

a) Rs.22599

b) Rs.23599

c) Rs.24599

d) Rs.25599

e) None of these

Click Here to View Answer
a)

According to question,

Principal of amount P=10000×27/100×12=32400

Principal of amount Q=10000×15/100×12=18000

Principal of amount R=10000×12/100×12=14400

Principal of amount S=10000×9/100×12=10800

Total amount of P=32400(1+(2×8)/100)=37584

Total amount of Q=18000(1+(3×10)/100)=23400

Total amount of R=14400(1+(3×6)/100)=16992

Total amount of S=10800 (1+(1×15)/100)=12420

Required answer,

The average=(37584+23400+16992+12420)/4=22599
