Explanation
1. let Arti age is 5x and Swati age is 4x
after 3 year
(5x+3)/(4x+3)= 11/9
on solving x=6
So Swati Present Age = 4*6= 24 year.
2. Let my age = x
ThenMy brother's age = x + 3
My mother's age = x + 26
My sister's age = (x + 3) + 4 = x + 7
My Father's age = (x + 7) + 28 = x + 35
Age my father when my brother was born = x + 35 – (x + 3) = 32
3. Rs.20000 after 4 years =20000(1+10/100)^4==Rs. 29282
Rs.20000 after 3 years=20000(1+10/100)^3=Rs. 26620
Rs. 20000 after 2 years =20000(1+10/100)^2=Rs. 24200
Rs.20000 after 1 year =20000(1+10/100)=Rs. 22000
Total amount after 4 years = 29282 + 26620 + 24200 + 22000 = Rs. 102102
4. Part filled by pipe A in 1 minute = 1/60
Part filled by pipe B in 1 minute = 1/40
Part filled by both pipes A and pipe B in 1 minute = 1/60+1/40=1/24
Suppose the tank is filled in x minutes
Then, To fill the tanker from empty state, B is used for x/2 minutes and A and B is used for the rest x/2 minutes
So X/2*1/40 + x/2*1/24=1
on solving x= 30 min
5. cost price = (524 + 436)/2 = 960/2 = Rs. 480
6. Let the number of questions attempted by Mohan with correct answers be x. Then, total marks obtained for correct answers = x * 1 = x
And the number of questions attempted by Mohan with incorrect answers = 30 – x.
Total marks deducted for incorrect answers = (30 – x)/4
Now, x – (30-x)/4 = 13.75
Or, 4x + x = 13.75 + 30 = 55 + 30 = 85 or, 5x = 85
x = 85/5 = 17
Incorrect answers = 30 – 17 = 13
7. Let the monthly income be Rs. X
Then, (x * 13)/100 = 305500
x = (305500 * 100)/13 = Rs. 2350000
Now, total monthly amount invested by Mr. Sharma = 29 + 9 + 13 = 51%
So, 51% of 2350000= (51*2350000)/100 = Rs. 1198500
8. Here in the given word GALOTIA, there are seven letters, where A appears twice. Hence the rqd number of ways
= 7!/2! = 3 * 4 * 5 * 6 * 7 = 2520

after 3 year
(5x+3)/(4x+3)= 11/9

So Swati Present Age = 4*6= 24 year.
2. Let my age = x
ThenMy brother's age = x + 3
My mother's age = x + 26
My sister's age = (x + 3) + 4 = x + 7
My Father's age = (x + 7) + 28 = x + 35
Age my father when my brother was born = x + 35 – (x + 3) = 32
3. Rs.20000 after 4 years =20000(1+10/100)^4==Rs. 29282
Rs.20000 after 3 years=20000(1+10/100)^3=Rs. 26620
Rs. 20000 after 2 years =20000(1+10/100)^2=Rs. 24200
Rs.20000 after 1 year =20000(1+10/100)=Rs. 22000
Total amount after 4 years = 29282 + 26620 + 24200 + 22000 = Rs. 102102
4. Part filled by pipe A in 1 minute = 1/60
Part filled by pipe B in 1 minute = 1/40
Part filled by both pipes A and pipe B in 1 minute = 1/60+1/40=1/24
Suppose the tank is filled in x minutes
Then, To fill the tanker from empty state, B is used for x/2 minutes and A and B is used for the rest x/2 minutes
So X/2*1/40 + x/2*1/24=1
on solving x= 30 min
5. cost price = (524 + 436)/2 = 960/2 = Rs. 480
6. Let the number of questions attempted by Mohan with correct answers be x. Then, total marks obtained for correct answers = x * 1 = x
And the number of questions attempted by Mohan with incorrect answers = 30 – x.
Total marks deducted for incorrect answers = (30 – x)/4
Now, x – (30-x)/4 = 13.75
Or, 4x + x = 13.75 + 30 = 55 + 30 = 85 or, 5x = 85
x = 85/5 = 17
Incorrect answers = 30 – 17 = 13
7. Let the monthly income be Rs. X
Then, (x * 13)/100 = 305500
x = (305500 * 100)/13 = Rs. 2350000
Now, total monthly amount invested by Mr. Sharma = 29 + 9 + 13 = 51%
So, 51% of 2350000= (51*2350000)/100 = Rs. 1198500
8. Here in the given word GALOTIA, there are seven letters, where A appears twice. Hence the rqd number of ways
