in March, let their individual savings be

a, b, c, and d ---> a+b+c+d = 1440

in April,

Oliver: 2a

Asia: b-30

Hassan: c

Abby: d+46

total = 2a + b-30 + c + d+46

= a + b + c + d + a + 16

= 1440 + a + 16 = 1456 + a

also: 2a = b-30 = c = d+46

b -30= 2a , ---> b = 2a+30

c = 2a

d+46 = 2a ----> d = 2a-46

so in a+b+c+d=1440

a + 2a+30 + 2a + 2a-46 = 1440

7a = 1456

a = 208

total in April = 1456+a = 1456+208 = 1664

check:

a=208, b=446 , c = 416, d = 370

March: 208+446+416+370 = 1440

April: 416+416+416+416 = 1664
