3/10 of her coin...
20c = 7u
50c = 3u
From the table... we know 20c have __9
From 1 to 100, 7 x 7 = 49, end with digit 9 only
Therefore 7u = 49
1u = 7
SO, 50c have 3u =3 x 7 =21
Total coins she have = 49+21 = 70 coins.
20c = 7u
50c = 3u
From the table... we know 20c have __9
From 1 to 100, 7 x 7 = 49, end with digit 9 only
Therefore 7u = 49
1u = 7
