a sum of money at simple interest amnt rs 2240 in 2 yrs and to rs 2600 in 5 yrs what is the principal amount |
|
Answer» Principal + interest for 2 YEARS = 2240 ---------1 Principal + interest for 5 years = 2600 --------2 Subtracting 1 from 2 = 2600 - 2240 = 360 interest for three years = 360 so interest for 1 year = 360/3 = 120 interest for 2 years = 2 x 120 = 240 Principal for 2 years = 2240 Interest for 2 years = 240 Principal = 2240 - 240 = 2000 |

Find the HCF of 65 and 117 . Write it in terms of 65m+117n. |
|
Answer» Using Euclid's DIVISION LEMMA : 117 = 65 * 1 + 52 => ( Equation 1 ) 65 = 52 * 1 + 13 => ( Equation 2 ) 52 = 13 * 4 + 0 Hence 13 is the HCF of 65 and 117. 13 = 65 m + 117 n From Equation 2 we can say that, 13 = 65 - 52 * 1 => ( Equation 3 ) From Equation 1 we can say that, 52 = 117 - 65 * 1 => Equation 4 Substituting the value of 52 as in Equation 3 in Equation 4. We get, 13 = 65 - ( 117 - 65 * 1 ) 13 = 65 + 65 - 117 13 = 65 * 2 + 117 * ( - 1 ) 13 = 65 m + 117 n => m = 2 ; n = ( - 1 ) |

OQ:PQ=3:4and perimeterof tiangle POQ=60cm. Find PQ QR AND OP |
|
Answer» Some part of the QUESTION is missing. The triangle given is a right ANGLED triangle. Having this as base we can solve it by the following : Let the side PQ = x OQ : x = 3 : 4 => OQ = 3x / 4 We know that, OQ² + PQ² = OP² X² + ( 3 X / 4 )² = OP² x² + 9x² / 16 = OP² Taking LCM we get, 16 x² + 9 x² / 16 = OP² 25x² / 16 = OP² => OP = √ ( 25x² / 16 ) = 5x / 4 => Perimeter = x + 3x / 4 + 5x / 4 = 60 cm Taking LCM we get, 4x + 3x + 5x / 4 = 60 => 12 x = 60 *4 => 12 x = 240 => x = 240 / 12 = 20 PQ = 20 UNITS OQ = 3X / 4 = 3 * 20 / 4 = 60 / 4 = 15 units OP = 5X / 4 = 5 * 20 / 4 = 100 / 4 = 25 units. Hence measures are : PQ = 20 ; OQ = 15 ; OP = 25 units. |

3x=7y-21, If (0, a) and (b, 0) are the solutions of the given linear equation. Find ‘a’ and ‘b’. |
|
Answer» HEY there !!! ___________________________ ===>>>>> Solution LET first write the given equation in its general form. ax + by = c .......( linear equation) Given equation, 3x = 7y - 21 3x - 7y = -21 ..........(general form ) Now, it is given that ... (0,a) and (b,0) are the solutions of the given equation. Case (I) ----------- Compare (0,a) with (x,y) HENCE the value we obtained are , x = 0. and y = a Now,put this values in the given equation we get, 3x - 7y = -21 3*0 - 7*a = -21 0 - 7a = -21 a = -21/-7 a = 3 ∴[ a = 3 ] Case (II) ----------- Now, compare (b,0) with (x,y) hence the value we obtained are , x = b and y = 0 Now, put this value in the given equation we get, 3x - 7y = -21 3*b - 7*0 = -21 3b - 0 = -21 b = -21/3 b = -7 ∴ [ b = -7 ] ___________________________ Let CHECK whether our answer is correct or not . we know that, (0,a) and (b, 0) are the solution of the given equation , (0,a) = (x,y) = (0,3) (b,0) = (x,y) = (-7, 0) 1.) Put x = 0 and y = 3 in the given equation 3x - 7y = -21 3*0 - 7*3 = -21 0 -21 = -21 -21 = -21 L.H.S = R.H.S 2.) Put x = -7 and y = 0 in the given equation , 3x - 7y = -21 3*(-7) - 7*0 = -21 -21 - 0 = -21 -21 = -21 L.H.S = R.H.S Proved ------------- ✴✴✴✴✴✴✴✴✴R.N.S✴✴✴✴✴✴ |
