In a plane, there are 16 non-collinear points. Then the number of straight lines formed is
Solution
To draw a line we need two points, selecting two out of 16 can be done in $$^{16}C_2$$=$$\dfrac{16*15}{2}$$=15*8=120.
So, there are 120 ways.
A student has to score 30% marks throughout. If he gets 30 marks and fails by 30 marks, then the maximum marks set for the examination is
Solution
Given that he got 30 marks, he must get an additional 30 marks to pass. So 30+30=60 marks are the pass marks.
It is given that 30% has to be scored by the student. So, 30% of the total marks is 60 marks.
Let x be the total marks.
30% of x = 60
$$\frac{30}{100}$$ *x=60
$$\RIghtarrow$$ x = $$\frac{60*100}{30}$$ = 200
A man bought 20 cows in ₹2,00,000. If the average cost of 12 cows is ₹12500, then the average cost of remaining cows will be?
Solution
Let the average cost of remaining 8 cows is x. It is given that the cost of all 20 cows is 2,00,000. And average of 12 cows 12,500. The cost of these cows is 12*12500=1,50,000.
The cost of remaining 8 cows is 8x.
So, 2,00,000 = 1,50,000 + 8x
$$\Rightarrow$$ 8x = 50,000
$$\Rightarrow$$ x = 6250
A sum at simple interest of $$13\frac{1}{2}%$$ per annum amounts to ₹3080 in 4 yr, then the sum is
Solution
Let us assume the amount is P.
Given the rate of interest is 13.5%.
The simple interest for 4 years is $$\frac{P*4*13.5}{100}$$= $$\frac{54P}{100}$$
P+$$\frac{54P}{100}$$ = 3040
$$\frac{154P}{100}$$ = 3040
$$\Rightarrow$$ P = 2000
The system of equation $$2x + 4y + 16 = 0$$ and $$3x + 6y + 24 = 0$$ is
Solution
The given system of equations is $$2x + 4y + 16 = 0 \Rightarrow 1$$ and $$3x + 6y + 24 = 0 \Rightarrow 2$$
Let's multiply equation 1 by three and equation 2 by 2.
We get $$6x + 12y + 48 = 0 \Rightarrow 1$$ $$6x + 12y + 48 = 0 \Rightarrow 2$$
Both the lines are collinear, and the number of solutions is infinite.
