Answer:
5:6
Step-by-step explanation:
given ratio = 3:4
let geometry cost = 3x
and calculator cost = 4x
given total cost = 350.
3x + 4x = 350
7x = 350
x = 350/7 = 50.
geometry price = 3(50) = 150
calculator price = 4(50) = 200 .
increase in price --
geometry price = 150 x 1/3 = 50
= 150 + 50 = 200 .
geometry new price = 200
calculator price = 200 x 1/5 = 40
= 200 + 40 = 240
calculator new price = 240
finding ratio of new prices --
geometry : calculator
200 : 240
20 : 24
5 : 6.
hence required answer is 5 : 6
