Question 76

A man, a woman and a boy together complete a piece of work in 3 days. If a man alone can do it in 6 days and a boy alone in 18 days, how long will a woman take to complete the work ?

Video Solution

Solution

Let the man's, woman's and boy's speed be x, y and z.
Let the piece of work be W.
Now, x+y+z = W/3
Also, x = W/6
and z=W/18
Therefore, y = W/3 - W/6 - W/18
y = W/9
Number of days required by woman alone to complete the work = W/y = W/(W/9)
Hence, number of days = 9
Therefore, the correct option is option A.

Question 77

If $$\sqrt{1296}$$ = 36, then the value of $$\sqrt{12.96}+\sqrt{0.1296}+\sqrt{0.001296}+\sqrt{0.00001296}$$ is:

Video Solution

Solution

Now, $$\sqrt{1296}$$ = 36
$$\sqrt{12.96}$$ = $$\sqrt{1296/100}$$ = $$\frac{36}{10}$$=3.6
Similarly,
$$\sqrt{0.1296}$$ = $$\sqrt{1296/10000}$$ = $$\frac{36}{100}$$=.36
$$\sqrt{0.001296}$$ = $$\sqrt{1296/10000}$$ = $$\frac{36}{1000}$$ = 0.036
Therefore, $$\sqrt{12.96}+\sqrt{0.1296}+\sqrt{0.001296}+\sqrt{0.00001296}$$ = 3.6+.36+.036 = 3.996
Option B is the correct answer.

Question 78

The perimeter of a circular and a square field are equal. What is the diameter of the circular field, if the area of the square field is 484 $$metre^{2}$$

Video Solution

Solution

Let the square of side be x,
Now area = 484
x^2 = 484, x=22
Perimeter = 4*22= 88
Circumference = 88
2*(22/7)*r = 88
Hence, r=14
Area= (22/7)*14*14 =616
Therefore, option C is correct.

Question 79

A papaya tree was planted 2 years ago. It increases at the rate of 20% every year. If at present, the height of the tree is 540 cm, what was it when the tree was planted ?

Video Solution

Solution

This problem can be viewed as that of compound interest.
Here, the trees growth is componded each year.
Now, let the original height be x.
540 = x*(1.2)^2
x = 375
Hence, the trees height was 375cm before 2 years.

Question 80

The ratio between the rates of travelling of A and B is 2: 3 and therefore A takes 10 minutes more than the time taken by B to reach a destination. If A had walked at double the speed, he would have covered the distance in

Video Solution

Solution

Let the speed of A and B be x and y.
Hence, (x/y) = 2/3
Also, let the distance be D.
Therefore, D/x - D/y = 10
Hence, we get D/x = 30
x = D/30
Now if the speed was double i.e 2x, time required to cover same distance= D/(2x) = D/(D/15) = 15 minutes.
Therefore, the correct option is option D.
