Question

Answer

Method 1 :
oranges : 3 units – 1 units = 2 units
apples : (378 – 3 units) + 14 = 392 – 3 units

392 – 3 units = 2 units/4
1568 – 12 units = 2 units
1 unit = 1568/(2 + 12) = 112
3 x 112 – (378 – 3 x 112) = 336 – (378 – 336) = 294

Method 2 :
oranges :
3u – 1u = 2u ——-> 4p
1u ——-> 2p

apples :
(378 – 3u) + 14 = 392 – 3u ——-> 1p
784 – 6u ——-> 2p

1u ——-> 784 – 6u
1u ——-> 784/(1 + 6) = 112
3u – (378 – 3u) = 3 x 112 – (378 – 3 x 112) = 294

Ans : 294 more oranges.

Can I express such way and do I need to change the apples?

You have made a number of mistakes using units and parts. My solution, using units and parts, is as follows :

Method 2 :
oranges :
3u – 1u = 2u ——-> 4p
1u ——-> 2p

apples :
(378 – 3u) + 14 = 392 – 3u ——-> 1p
784 – 6u ——-> 2p

1u ——-> 784 – 6u
1u ——-> 784/(1 + 6) = 112
3u – (378 – 3u) = 3 x 112 – (378 – 3 x 112) = 294

1u – 14 + 4u / (2/3) = 378
                     1u + 6u = 378 +14
                              7u = 392
                              1u = 392 / 7 = 56
56 – 14 = 42
378 – 42 – 42 = 294 as the answer.
