-3/10+7/11-3/14

5/21-2/14

2/6

Answer 2

Answer:

METHOD - 1

we take (x,y=x2+y)

this is corresponds with the data given, since:

12+1=1+1=2

22+3=4+3=7

32+4=9+4=13

52+6=25+6=31

Therefore, the answer for (12 , 11) should be

122+11=144+11=155

METHOD - 2

we take (x,y=xy+1)

this again, corresponds with the given data, as:

1×1+1=1+1=2

2×3+1=6+1=7

3×4+1=12+1=13

5×6+1=30+1=31

Going with this method the answer will be

12×11+1=132+1=133
