Siblings

Three siblings had saved up a total of 1,274 CZK. Peter had saved up to 15% more than Jirka and Hanka 10% less than Peter. How much money they saved each one of them?

Correct result:

h =  414
j =  400
p =  460

Solution:


p+h+j=1274
p = 1.15 j
h = 0.90 p

p+h+j=1274
p = 1.15•j
h = 0.90•p

h+j+p = 1274
1.15j-p = 0
h-0.9p = 0

h = 414
j = 400
p = 460
