Tamarind Seeds
Sunita took some tamarind (imli) seeds. She made groups of five with them and found that one seed was leftover. She tried making groups of six and groups of four. Each time one seed was leftover. What is the smallest number of seeds that Sunita had?
उत्तर
ON making 4, 5, and 6 one seed is left behind each time.
So, to find the smallest number of seeds that Sunita had, we will first calculate the LCM of 4, 5, and 6 and then add 1 to it.
LCM of (4, 5, 6) = 60 Adding 1 to it, we get 61.
Hence, the smallest number of seeds that Sunita has is 60 +1 = 61

Think of a number. If it is a multiple of 3 write it in the red circle. If it is a multiple of 5 write it in the blue circle.
Some numbers are multiples of both 3 and 5.
So we can say that they are common to both 3 and 5.
Think! If you write the multiples common to 3 and 5 in the purple part, then will they still be in both the red and the blue circles?
