Malti donate 1/ 20 of her salary to a widow ashram.1/3of her salary was spent on school fee of the children ,1/6 of the salary on food .After these expenses she was left with RS. 21000 find her salary |
|
Answer» Answer: 46,666.667 Step-by-step explanation: First, you have to find a common MULTIPLE of 20, 3, and 6, I use 60. Next, you have to CONVERT each fraction to have a denominator of 60: 1/20*3/3 = 3/60 1/3*20/20 = 20/60 1/6*10/10 = 10/60 Then, you want to find what fraction Malti didn't spend: (3+20+10)/60 = 33/60 (60-33)/60 = 27/60 Now, we know that 21000 = 27/60x (x being her salary) so we can SIMPLIFY in terms of x: (27/60)x = 21000 *60 27x = 1260000 /27 x = 46666.666.... Therefore, Malti's salary is 46,666.667 |

Prove that x^2- x is divisible by 2 fore all the positive integer x |
|
Answer» Step-by-step EXPLANATION: this is probably not the book PROOF but it's a LOGICAL proof x^2-x = x(x-1) now if x is odd in x(x-1), x-1 would be EVEN or 0 and therefore divisible by 2 if x is even then in x(x+1) we get x as even which implies it is divisible by two |

Can two numbers have 10 as their HCF and 300 as their LCM? Give reason |
|
Answer» Yes, we can have 10 as HCF and 300 as LCM of any two natural numbers. This is explained as follow :- In MATHEMATICS, there is a rule that thej HCF of any two number must be a factor of LCM or LCM must be a multiple of HCF. i.e. LCM ÷ HCF gives REMAINDER zero If this is not satisfied then the given condition is wrong. e.g. Two numbers can have 12 as LCM and 4 as HCF because 12 is DIVISIBLE by 4 while two numbers cannot have 16 as LCM and 3 as HCF because 3 is not factor of 16. Now in the question HCF is a factor of LCM i.e. 10 is a factor of 300 Hence two numbers can be exist i.e. real number because it satisfy the condition. |
