Hi - Please treat this as urgent. Wondering if I can get examples/Samples/Animated Video to cover the concepts for the following scenario -
1) 20 men take 50 days to complete a tasks .How many days 10 men will take? (In this example - key is 1 man will take more days and hence for 10 men it is (50*20)/10 ) . Below example is slightly diff -
2) I can buy 50 pencil in 100 rupees. How many pencil can Ibuy in 30 rupees? (In this example - identifying a unit will require a dvidie unlike for above example identifying days for 1 men will require multiply).
Hope this is clear. Need animated way of explaining this to my son.

| MEN | DAYS |
| 20 | 50 |
| 10 | x |
Since men and days are inversely proportional, so we get
20 50 = 10 x
(2).
| pencils | amount(Rupees) |
| 50 | 100 |
| 30 | x |
Since amount and pencils are directly proportional, so
