For the following questions answer them individually

Question 11

5 pencils and 4 erasers cost Rs 13 whereas 9 pencils and 5 erasers cost Rs 19 Then the price of 6 pencils and 3 erasers is

Video Solution

Solution

5p + 4e = 13

9p + 5e = 19

solving for p, we get p = 1

e = 2

So, 6 pencils and 3 erasers cost

6 x 1 + 3 x 2 = 12

Question 12

Let $$a_{1}, a_{2}.........a_{7}$$ be arbitrary different positive integers taking one value at a time from 1,2,........7. The number $$(a_{1}-1) (a_{2}-2)......(a_{7}-7)$$

Video Solution

Solution

If $$a_{1}, a_{2}.........a_{7}$$ are different positive integers taking one value at a time from 1,2,........7. The number $$(a_{1}-1) (a_{2}-2)......(a_{7}-7)$$ will always be zero as one of the numbers will be equal to 1, 2, 3.... 7.

Question 13

Consider the natural numbers 88935. Then the least natural number by which we can divide or multiply the number to make it a square number is

Video Solution

Solution

88935 can be written as 5929 x 15

5929 is the square of 77

So, the answer is 15

Question 14

There is a path 1 m wide outside a rectangular field of 16 m length and 11m breadth then the total area of the path is

Video Solution

Solution

The area of the bigger rectangle is 18 x 13

The are of the smaller rectangle is 16 x 11

The required value is 18 x 13 - 16 x 11 = 58 sq.m

Question 15

A two digit is such that when it is divided by the largest single digit prime number leaves remainder 4.If the difference of the two digit is 4 then the number is

Video Solution

Solution

If the difference between the digits has to be 4, only 73 and 95 qualify. Of these 73 leaves a remainder of 3 and not 4 when divided by 7. So, the answer is 95.

Question 16

A train runs at the speed of 72 Km per hour The distance between any two stations is 42 km and the train stops at each stations for 5 minutes. Then the time taken by train to go 350 km is

Video Solution

Solution

-Number of stations in 350 kilometers = 350/ 42 = 50/6 = 8 stations.

Time stopped at stations = 8 x 5 = 2/3 hrs

Time taken for travel = 350/72 + 2/3 = 5 hours 31 minutes 40 seconds
