Quantitative Aptitude

21. 19 people went to a hotel for a combined dinner party. 13 of them spent Rs 79 each on their dinner and the rest spent Rs 4 more than the average expenditure of all the 19. What was the total money spent by them?

A. 1628.4

B. 1536.07

C. 1492

D. 1496.4

Solutions

Let us suppose that the average expenditure of the party is x.

Given that:

13 of them spent Rs 79 and the rest spent Rs 4 more than the average expenditure of all the 19.

So, the equation becomes

∴ 13 × 79 + 6 (x + 4) = 19 × x

Now since there were 19 people

So, Total expenditure of the party = 80.84 × 19

= Rs.1536.07

22. While calculating the average of eight 2-digit numbers, a student mistakenly interchanged the digits of a number as a result the average becomes 9 less than the original average. What is the difference of two digit of that number?

A. 6

B. 7

C. 4

D. 8

Solutions

Let the unit and tenth digit of the original number is y and x respectively. Then, the original number is (10x+y) and interchanged digit number is (10y+x). Let the sum of remaining seven numbers is S and the original average is A. Then,

S+(10x+y)=8A……(i)
and

S+(10y+x)=8(A-9)
S+(10y+x)=8A-72……(ii)

Subtracting second from first we get

10x+y-10y-x=72
9x-9y=72
x-y=8

A. 600

B. 500

C. 450

D. 350

Solutions

Let total students =x

We solve such questions using Venn- Diagram as shown below

From venn diagram we can observe that number of students who passed in at least one subject is = 35% + 15% + 40 % = 90%

Number of students who failed in both subject = 100% – 90% = 10%

A.T.Q.

10% of x = 60

A. I am cooking since an hour.

B. Burger and chips are my favorite dish.

C. My mother unlike my aunts are very lenient.

D. There is no tea, is there?

Solutions

Key-Points

Here, option 4 is correct for the following reasons:

In option 1, ‘I am cooking since an hour’ is wrong. It is because here the action is already started (cooking) and is still going on, so, Present Perfect Continuous Tense will be used. Also, instead of ‘since’, ‘for’ will be used as it denotes a period of time (hour), and ‘since’ represents a point of time.
- The correct usage should be ‘I have been cooking for an hour.’
In option 2,‘are’ is wrong. It is because if two or more than two nouns or adjectives are joined by ‘and’ but only person or thing or idea is discussed, a singular verb is used.
- The correct usage should be ‘Burger and chips is my favorite dish.’
In option 3, ‘are’ is wrong. It is because if the subject is joined by ‘unlike’, the verb will agree with the first subject.
- The correct usage should be ‘My mother unlike my aunts is very lenient.’

Therefore, here we find that option 4 is grammatically correct and hence the correct answer.

Additional Information

If the subject is joined by the following words/phrases, the verb will agree with the first subject:
- As well as, with, along with, together with, and not, in addition to, but, besides, except, rather than, accompanied by, like, unlike, no less than, nothing but, etc.
