Find the smallest number which which divided by 28 and 32 leaves remainders 8 and 12 respectively. |
|
Answer» Given that the smallest number when divided by 28 and 32 leaves remainder 8 and 12 respectively.28 - 8 = 20 and 32 - 12 = 20 are divisible by the required numbers.Therefore the required number will be 20 less than the LCM of 28 and 32.Prime factorization of 28 = 2 × 2 × 7Prime factorization of 32 = 2 × 2 × 2 × 2 × 2LCM(28,32) = 2 × 2 × 2 × 2 × 2 × 7 = 224.Therefore the required smallest number = 224 - 20 = 204.Verification:204/28 = 28 × 7 = 196. = 204 - 196 \xa0 = 8204/32 = 32 × 6 = 192 = 204 - 192 = 12. Answer is 20 204.. |

Find two consecutive odd positive integers sum of whose squares is 290 |
|
Answer» Let one of the odd positive integer be xthen the other odd positive integer is x+2their sum of squares = x² +(x+2)² = x² + x² + 4x +4 = 2x² + 4x + 4Given that their sum of squares = 290⇒ 2x² +4x + 4 = 290⇒ 2x² +4x = 290-4 = 286⇒ 2x² + 4x -286 = 0⇒ 2(x² + 2x - 143) = 0⇒ x² + 2x - 143 = 0⇒ x² + 13x - 11x -143 = 0⇒ x(x+13) - 11(x+13) = 0⇒ (x-11) = 0 , (x+13) = 0Therfore , x = 11 or -13We always take positive value of xSo , x = 11 and (x+2) = 11 + 2 = 13Therefore , the odd positive integers are 11 and 13 . Required numbers= 11 and 13 |

The product of two successive integral multiples of 5 is 300 . Determine the multiples. |
|
Answer» Let one number be x, so that the other number is x+5.According to the given question,x(x+5)=300x2+5x-300=0(x+20)(x-15)=300x=-20 and x=15 x cannot be negative, since the numbers are successive integral multiples of 5.So, x=15, and x+5=20Hence, the multiples are 15 and 20. Required numbers = 15 and 20 |

1÷a+b+c=1÷a+1÷b+1÷x |
| Answer» Here we have1/a+b+c=1/a+1/b+1/xSo by shifting x terms to one side1/a+b+c-1/x=1/a+1/bBy taking the LCM of both the sidesx-(a+b+x)/x(a+b+x)=a+b/abx-a-b-x/x(a+b+x)=a+b/ab (x-x=0)-a-b/x(a+b+x)=a+b/ab. -(a+b)-(a+b)/x(a+b+x)=a+b/ab. (-(a+b)=(a+b) ( -1=1)-1/x(a+b+x)=1/abCross multiply-ab=x(a+b+x)-ab=xa+xb+x2By shifting -ab to the other side x2+xa+xb+abBy taking commonx(x+a)+b(x+a)(x+a) (x+b)So x=-a or x=-b | |
