Hi,

Let's try:

Let March salary → 100 u
March savings → 25 u
April salary → 80 u
April savings → 25 u

% is (25/80) × 100 % = ???


Can you solve from here?

Hope this helps.

Hi,

You may have noted that

(1) this is a "double if" or 2 scenario question
(2) the total sum remained the same

First Scenario

You already established that the ratio of

Tony : Alan : Total
10 : 2 : 12

Second Scenario

The key lies in understanding/interpreting the statement "....40% more than..."

In this case, the ratio of

Tony : Alan : Total
100 : 140 : 240
5 : 7 : 12


From (2), the Total is now the same, i.e. 12.

So, can you see that,

5U --> 300
10U --> 600

y = 180 - 70 - 31 = 79 degree

Angle XZY = 180 - 70 - 79 = 31 degree

w = 180 - 77 - 29 - 31 = 43 degree

43 + 79 = 122 degree

Angle y -> 180 - 31 - 70 = 79 degrees
180 - 77 - 31 = 72
180 - 72 = 108
Angle w -> 180 - 108 - 29 = 43 degrees
Angle w + Angel y -> 43 + 79 = 122 degrees
Ans : 122 degrees
