The Area of a right angle triangle is 1/2X^2 +2x +3/2, what is its height, if it is given that height is more than

base?

• We know that the area = ½ * base * height

• Let us look at the area: • ½ X^2 +2X+3/2 or ½ (X^2 +4X+3)

• Or ½ (X^2 +3X +X +3)

• =1/2 (X(X+3) +1(X+3))

• =1/2 ((X+3)(X+1)) thus base and heights are (x+1) and (X+3) respectively. Ans.


If (X+1) is HCF of (AX^2+bX +C) and (BX^2 +AX+C), then what is

the value of C? • Both the numbers are divisible by (X+1)

because it is HCF (Heightest Common Factor).

• X = -1. thus if we put the value of X as -1, it will equate the equation to Zero

• AX^2+bX +C = 0 (if X = -1)• A – B +C =0 • BX^2 +AX+C or B – A + C = 0 OR C=0


IF (X-1) IS HCF OF (X^2-1) AND (PX^2-Q(X+1)) THEN WHAT IS P?• X = 1, so if we put the value of X as 1, it

will make the equation equal to zero.

• (PX^2-Q(X+1)) = 0• P – Q- Q = 0

• P – 2Q = 0

• P = 2Q answer.


If 6/X + 3/Y = 7 and 3/X +9/Y =11, then what is the value of X?

• Let us assume that 1/X = W and 1/Y = U

• 6W+3U = 7

• 3W +9U= 11 (Multiply 2nd equation by 2)• 6W +18 U = 22

• By comparing the first and 2nd equation, we get : 15U = 15 or U = 1 or Y=1; putting the value in first equation, we get:

• 6W +3 = 7 or 6W = 4 or W = 2/3; X = 3/2


3X+5Y = 0 and KX+10Y = 0, what is the value of K, if there are more

than 1 solutions? • Take 3 from first equation and K from 2nd

equation and 5 from first equation and 10 from 2nd equation.

• 3/K = 5/10• Solving this, we get:

• 5K = 30

• OR : K = 6 answer.


2X+3y – 5 = 0 ; 4X+KY-10 =0 AND THERE ARE

INFINITE NUMBER OF SOLUTIONS, THEN WHAT IS K?

• 2/4 = 3/k = -5/-10

• K = 6


2X+3y – 5 = 0 ; 4X+KY-Z =0 AND THERE NO

SOLUTION, THEN WHAT IS K & Z?

• A1/A2 = B1/B2 IS NOT EQUAL TO C1/C2

• =2/4 = 3/K is not equal to -5/Z

• Thus K = 6, but Z should not be equal to 10 , Z can take any other value. Ans.


2X+3y – 5 = 0 ; 4X+KY-10 =0 AND THERE IS A

UNIQUE SOLUTION, THEN WHAT IS K?

• A1/A2 SHOULD NOT BE EQUAL TO B1/B2

• THUS 2/4 SHOULD NOT BE EQUAL TO 3/K

• THUS K CAN TAKE ANY OTHER VALUE OTHER THAN 6 ANSWER


WHAT IS THE VALUE OF (8)^5/3 ?

• LET US SOLVE IT AS : ((8)^1/3)^5

• = ((2*2*2)^1/3)^5

• =2^5• =2*2*2*2*2 = 32 ANSWER.


WHAT WILL YOU GET BY SOLVING 625^-3/4?

• In order to solve the power of negatives, we will solve it as:

• (1/625) ^3/4• Now we will first solve ¼ and then 3

• =((1/625) ^1/4)^3

• =1/5^3

• =1/125 answer.


There are 50 tickets from 1 to 50. One ticket is drawn at random,

what is the probability that it is in multiple of 2 or 3?

• 50/2 = 25

• 50/3 = 16.66• 50/6 = 8.3

• Thus add 25+16 – 8

• = 33 / 50 answer.


In how many ways 5 persons sit on a round table containing 5 chairs? • (n-1)!

• =4*3*2*1

• =24 answer.


Which is the biggest: (2)^1/2, 3^1/3, 5^1/5 answer?

• 3^1/3 answer.


A,B,C start with equal capital. A leaves the business after 4 month. B doubles his capital after 6 month.

After 12 month, what is the profit sharing ratio among A,B,C for the

year? • Let us assume that each had 1 Rupee. • A = 1*4 month• B = 1*6 + 2*6 month

• C = 1*12 month = 4: 18: 12 or • =2:9:6 answer.
