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.

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

Angle XZY = 180 - 70 - 79 = 31 degree

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

43 + 79 = 122 degree

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

Let's try.

If there are 4 pupils, everyone plays for 30 mins each.

If there are 8 pupils, everyone plays for 15 min each.

Hope this helps.
