Explanation

Aslam's shells = x

Ali's shells = x + 80% of x = x + 0.8x = 1.8x

Since Ali's shell collection share is 80% more than Aslam's, we can set up the equation:

1.8x - x = 50 (given)

0.8x = 50

x = 62.5 (Aslam's shells)

Aslam has 80 more shells than Ali, so:

Aslam's shells = Ali's shells + 80

x = 1.8x - 80

x = 180 - 80

x = 100 (Aslam's shells)

Now, let's find Ali's shells:

Ali's shells = 1.8x = 1.8(100) = 180

Total shells = Aslam's shells + Ali's shells

= 100 + 180

= 280 + 440 (since 50 Ali shell collection share is 80% more than Aslam, we need to add 440 to get the total)

= 720
