Q1.
Mr Krishna packages perfumed oils in different sized bottles. During a festival, the following customers asked for 1 l perfumed oils but in different sized bottles. Write the number of bottles each of them will get. a) Ms Shetty wants bottles of 500 ml each b) Mr Muthukumar wants bottles of 200 ml each c) Ms Naini wants bottles of 100 ml each d) Ms Kannan wants bottles of 50 ml each
Answer
Every customer gets 1 l, and 1 l = 1000 ml. So each time we ask: how many of these small bottles make 1000 ml?
| Customer | Bottle size | Counting | Bottles |
|---|---|---|---|
| a) Ms Shetty | 500 ml | 500, 1000 | 2 |
| b) Mr Muthukumar | 200 ml | 200, 400, 600, 800, 1000 | 5 |
| c) Ms Naini | 100 ml | 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 | 10 |
| d) Ms Kannan | 50 ml | two 50 ml make 100 ml, and 1000 ml has ten 100 ml → 10 × 2 | 20 |
a) 2 b) 5 c) 10 d) 20
Why it happens: The oil is the same 1000 ml every time. Smaller bottles hold less, so more bottles are needed to hold the same oil.
Tip: Check each answer by adding back: 5 × 200 ml = 1000 ml, 20 × 50 ml = 1000 ml.
