Here’s an example for a similar question. Please refer to the slide.
When students are able to understand the logic behind the solution, MD might not be necessary.
Another question for your kid to practise.
Miss Lim bought a packet of sweets to distribute to her class. If each child gets 3 sweets, she would be left with 30 sweets. If each child gets 4 sweets, she would need 5 more sweets.
a) How many children are there in the class
b) How many sweets did Miss Lim have at first.
The solution to your question, in order to send the same companies 1 more ticket (4 -3), Mr Tan needs 70 (50+20) charity tickets.
Number of companies ------ 70/1 ------ 70
Number of tickets ----- (70*3) + 50 ----- 260
Hope this helps.
