Weight of 1 apple = 500 g
Weight of 6 apples = 500 * 10
= 5 kg

Initial weight = 25 - 5
= 20 kg
Number of apples in his carton initially :
= 20000/500
=40 apples

you can try every answer choice here.

for me, i did 0.007896 - answer choice a, or 0.001008, and got the square root of the difference, which did not work, so (a) is wrong.

i did the same for each choice, and it worked for d, as 0.007896 subtracted by 0.001007 is 0.006889, and the square root of 0.006889 is 0.083.

 

First Prime Factorize 98800, that Gives;

98800 = 2×2×2x2x5×5×13×19

As factor of 13x17 is not in Pair.

98800 should be divided by 13x17 to get a Perfect Square

i.e.- 98800/13x17  = 400

Multiply 10000 to both numerator & denominator
(0.0265 x 10000)/(1 x 10000) = 265/10000
It can be written as 2.65% = 2.65/100 or 265/10000

find LCM (Least Common Multiple) for 265 & 10000.
5 is the LCM for 265 & 10000

divide numerator & denominator by 5
265/10000 = (265 / 5) / (10000 / 5)
= 53/2000

The plumber has to make 25 pieces from 1 meter.
So for 1 piece,  the measurement will be 1/25=0.04 m
from 50 m plumber can get 50/0.04 = 1250 pieces

1) 49863/17 = 2933.1,Dividend contains 2 places of decimal So,498.63 / 17=29.33
2) 16750/32 = 523.43 ,Dividend contains 2 places of decimal So,167.50/32 = 5.23
3) 57565/43 = 1338.72,Dividend contains 2 places of decimal So,575.65/43 = 13.38
Since 29.33>13.38>5.23 ,the desired order is 1,3,2.

Given , 0.6x0.225x0.9x0.125x24
it can be written as :

Let x + 741 + 7.41

= 801.2

Then, x = 801.2 - (741 + 7.41)

= 801.2 - 748.41 =52.79

Missing digit = 52.79

Required decimal=1/30×365=1/10950=.00009

0.125 + 0.100 = 0.225 = 225/1000 = 9/40.
Sum of the numerator and denominator is 9 + 40 = 49
