Here the bigger number is 20000
Smaller number is 4632
Now, subtracting 4632 from 20000
20000 - 4632 = 15368 and the resut is an even number.
Hence, The difference between 4632 and 20000 is 15368 and is an even number.
Correct Answer: 4
Explanation:
The smallest value will be obtained by giving x the smallest possible value while y gets the largest possible value. The smallest value for x = 7. This means that y will have to be less than or equal to 3 (so that x + y <11), but we want the largest value of y which is 3.
The difference, x - y will be 4.
Correct Answer: 6 painters
Explanation:
Two painters can complete two rooms in two hours.So 18 rooms can be painted in 6 hrs by 6 painters
Correct Answer: 0.4
Explanation:
Let the weight of the empty tin = w
(2 - w) = weight of the cookies; and one quarter of the cookies weigh (2 - w)/4
One quarter of the cookies + tin = 0.8 = w + (2 - w)/4
Multiply through by 4; 3.2 = 4w + 2 - w
1.2 = 3w; w = 0.4
Correct Answer: 125
Explanation:
Let the number be x. Then, x - 3x/5 = 50 <=> x = (50 * 5) / 2 = 125..
