Question

ANSWER THE FORTH ONE WITH FULL SOLUTION. 4TH PLEASE FULL SOLUTION.

Answer 1

Let the total apples be a

Number of Apples sold + Number of apples left = Total number of apples

=> 40 % of a + 420 = a

=> 40a/100 + 420 = a

=> 420 = a - 40a/100

=> 420 = (100a - 40a) / 100

=> 60a = 42000

=> a = 700

Total number of apples = 700

Answer 2

let the total apples be a number of apples sold + number of apples left= total no of apples =>40% of a+420=a
40a/100+420=a =>420=a -40a /100=>420
(100a- 40a) /100 => 60a=42000
=>a= 700
Total no of apples =700♥♥♥
