Anjan Karthi 4 years, 3 months ago

Mass of solution W = 250 g. Density of solution D = 1.5 g/mol. Therefore, volume of solution = W / D = 250 / 1.5 = 166.6 cm^3. Hence, W / V% = 40 × 100 / 166.67 = 23.99 %. //

Question : The difference between two numbers is 35489. if greater number is 73325, find the sum of the two numbers

Posted by Bhavesh Bhati 4 years ago

CBSE > Class 04 > Mathematics

1 answers

Sia ? 4 years ago

Given largest number is 73325.
let x be smallest number 73325 - x = 35489 (difference is 35489).
Therefore x = 73325 - 35489 = 37836.
Therefore the smallest number is 37836.
The sum of the largest and the smallest numbers is 73325 + 37836 = 111161.
