Wa alaykum salam,


Masha'Allah that's correct.


Here's the solution:
80,000 divided by 10 = 8,000; divided by 4 = 2,000; divided by 2 = 1,000; times 2 = 2,000


Duaas requested.
Wassalam

Nice riddle. A niftier way of calculating it is to multiply the denominators of the fractions : 2 x 4 x 10 = 80. 80'000/ 80 = 1000. Then double to get the answer, 2000.

i totally agree with you queenie, better to watch others wreck their brains, seems like too much thinking and hardwork.
