The Middle school won 17 games so the senior school won 51 games
Cost of lack increased by 30%
new cost of lack will be = 100% + 30% = 130%
We are given that new cost = £65
Thus 130% of original cost = 65
100% of original cost = 65 × 100/130 = £50
Thus original price was £50
500 in 2:3 is saying that there are five different parts (2 + 3)
This means that 500 needs to be split into five, which is 100.
After that all you need to do is put 2 'sections' on one side and 3 on the other.
For example, 2 : 3 = 2( x 100) : 3( x 100)
= 200 : 300
<span>In a triangle the sum of two sides is always greater than the third side.
</span><span>A:12,9,21
</span><span>12+9 = 21
21 = 21 </span>⇒ no
<span>B:7,6,12
</span>7+6 = 13
13 > 12 ⇒ yes
<span>C:3,8,14
</span>3+8 = 11
11 < 14 ⇒ no
<span>D:23,13,37
</span>23+13= 36
36 < 37 ⇒ no
Answer: <span>B:7,6,12</span>
