is it 105 and did it in 15 sec. Here it goes when he got 30% he failed by 15 marks but when he got 45% he passed by 30 marks. so by the difference of 45%-30% the marks were 15+30=45 marks.

so when 15% = 45 marks, 30% should be 90 marks and + 15 for the pass marks. 90+15=105. I think I didnt explain properly, is it so Sunnyboy

I did it the traditional way:


M*0.3=P-15
M*0.45=P+30

(P-15)*0.45=(P+30)*0.3
(P-15)*1.5=(P+30)
0.5P=52.5
P=105

I think it took me about a minute...
