Best answer
After 1 bottle is purchased at 520 baht, 2nd and 3rd will be priced as 364(70% of 520) each.

Total price = 1248 bahts.

As they will share the price equally, each of them have to pay : $\frac{1248}{3}$ = 416 bhats.

M pays : 4 Eu + 27 Bhats = 4*46 + 27 = 211 bhats

M should pay 416 - 211 = 205 Bhats.

That is $\frac{205}{41}$ Dollar = 5 Dollars.

Answer should be C.
