1.

Find the value of (14.7 X 15.3)

Answer»

( 14.7 ) × ( 15.3 )


=> ( 15 - 0.3 )² × ( 15 + 0.3 )


We KNOW, ( a - B ) ( a + b ) = a² - b²


=> 15² - 0.3²

=> 225 - 0.09

=> 224.91

2.

two equal sides of a triangle are each 5 meters less than twice the third side.if the perimeter of the triangle is 55 meters find the length of its sides?

Answer»

Let the unequal side be ( X ) m

Each Equal side = ( 2x - 5 ) m

Perimeter = 2( 2x - 5 ) + x

55 = 4x - 10 + x

65 = 5x

13 = x

Length of unequal side =13 m
Length of equal sides = 26 - 5 = 21 m

Ram gets 49℅ marks obtaining 294 marks . the percentage of marks obtained by his sister is 372?

Answer»

Total MARKS be ( X ),


49% of x = 294

=> 49x/100 = 294

=> x = ( 294 × 100 )/49

=> x = 600



Hence, total marks = 600





% of his sister = ( 372 × 100 ) /600

% of his sister = 372/6

% of his sister = 62%

Find the value of p for which the quadratic equations x(x-4)+p=0 has real roots

Answer»

<P>x(x - 4) + p = 0 can be REWRITTEN as x^2 - 4x + p = 0, or (x^2 - 4x + 4) - 4 + p = 0.

x^2 - 4x + 4 = (x - 2)^2

Thus, (x - 2)^2 = 4 - p. This equation yields real SOLUTIONS if and only if 4 - p >= 0 (since the square of a real number is NONNEGATIVE), so p <= 4.

After selling 55% of mangoes, a fruitseller still has 90 mangoes. find the number of mangoes he initially had.

Answer»

Let the total NUMBER of mangoes be x


a - ( 55% of a ) = 90

=> a - 55a/100 = 90

=> ( 20a - 11a ) = 90×20

=> 9a = 90 × 20

=> a = 200





Total number of mangoes = 200

The difference between the two numbers is 983563.if the greater number is 1398357,find the smallest number

Answer»

Question :- The difference between the two numbers is 983563. if the greater number is 1398357,find the smallest number ?

Solution :-

given that, The difference between the two numbers is 983563 and the greater number is 1398357 .

Let us assume that, the smallest number is X.

Than,

→ greater number - SMALLER number = 983563

→ 1398357 - x = 983563

→ x = 1398357 - 983563

→ x = 414794 (Ans.)

Hence, the smallest number is 414794 .

VERIFICATION :-

→ greater number - smaller number = 983563

→ 1398357 - 414794 = 983563

983563 = 983563 (Verified.)

If the angles of a quadrilateral are x°,x-20°,x-30°,x+10°, then find x

Answer»

Sum of all angles of an quadrilateral = 360°


=> x + x - 20 + x - 30 + x + 10 = 360


=> 4X - 40 = 360

=> x - 10 = 90

=> x = 100°




Angles are :-

x = 100°
x - 20 = 80°
x - 30 = 70°
x + 10 = 110°

Answer»

Let the THIRD SIDE be a
Perimeter is sum of all sides
55= a+( sum of other TWO sides)
Other two sides are EQUAL and 2a-5 ( 5m less than TWICE the third)
a+2a-5+2a-5=55
5a-10=55
5a=55+10
a=65/5=13
Hence the length of the side is 13m
