Given :-
Renuka bought bananas in the ratio
3 : 7: 5 on three particular day
On third day, Renuka bought 55 bananas
Solution 1 :-
Let the ratios be 3x, 7x and 5x
Here, we know that,
On third day Renuka bought = 55 bananas
Therefore,
5x = 55
x = 55/5
x = 11
Thus,
On first day Renuka bought = 3x
= 3 * 11 = 33
On second day Renuka bought = 7x
= 7 * 11 = 77
On third day Renuka bought = 5x
= 5 * 11 = 55
Hence The total number of bananas
= 33 + 77 + 55 = 165
Solution 2 :-
Let the ratios be 3x, 5x and 7x
We know that,
Renuka bought 55 bananas on third day
Therefore ,
5x = 55
x = 55/5 = 11
On first day Renuka bought 3x
= 3 * x = 33 bananas
On second Renuka bought 7x
= 7 * 11= 77 bananas
Hence, The total number of bananas of other two days,
33 + 77 = 110 bananas
