C18

D81

| | Important Formulas | Topic: | Asked In Wipro |

Explanation:

x+y = 8 -----(1)
(10y+x) - (10x+y) = 54 => 9y-9x = 54
y-x = 6 -------(2)
By solving eq. (1) and (2)
y = 7 and x = 1

The average age of 30 students is 9 years .If the age of their teacher is included ,it becomes 10 years . The age of the teacher (in years ) is :

A27

B31

C35

D40

| | Important Formulas | Topic: | Asked In Wipro |

Explanation:

Given 30 students avg. age = 9 years.
So total age of 30 students = 9*30 = 270 years.
Teacher's age included.
So, avg. of 30 students + one teacher = 10 years.
=> Total age of 30 students + one teacher = 10 * 31 = 310 years.
Therefore age of teacher = (310-270) = 40 years.

The average age of 24 boys and the teacher is 15 years. When the teacher's age is excluded, the average decreases by 1. What is the age of the teacher ?

A38 years

B39 years

C40 years

| | Important Formulas | Topic: | Asked In Wipro |

Explanation:

Given one teacher + 24 students avg. age = 15 years.
So total age of one teacher + 24 students = 15*25 = 375 years.
Teacher's excluded
So, 24 students avg. age = 14 years.
=> Total age of 24 students = 24 * 14 = 336 years.
Therefore age of teacher = (375-336) = 39 years.

Sixteen men can complete a work in twelve days. Twenty four children can complete the same work in 18 days. 12 men and 8 children started working and after eight days three more children joined them. How many days will they now take to complete the remaining work?

A2 days

B4 days

C6 days

D8 days

| | Important Formulas | Topic: | Asked In Wipro |

Explanation:

Lets assume Men as "M" and children as "C" .
So as per the Question
16M*12 = 24C*18
=> M/C=9/4
Total work= 16*9*12
Lets assume days required to complete remaining work = x days.
(12*9+8*4)*8+(12*9+11*4)*x=16*9*12
x=608//152 = 4 days.

A vessel is full of a mixture of spirit and water in which there is found to be 17% of spirit by measure. Ten litres are drawn off and the vessel is filled up with water. The proportion of spirit is now found to be 15 1/9%. How much does the vessel hold?

A70 litres

B90 litres

C80 litres

D85 litres

| | Important Formulas | Topic: | Asked In Wipro |

Explanation:

In 10L of water drawn amount of spirit present is = (17/100)*10 =1.7 L .
Lets assume x is the capacity of the vessel
from 17% amount of spirit comes down to 15 1/9% .
The difference between this percentage is (17% - 15 1/9%) = 17/9 % x
17/9 % x =1.7 litres .
=> x = 90 L
