if
2+3=8,
3+7=27,
4+5=32,
5+8=60,
6+7=72,
then
7+8=??

Solve it?

• 
  2*(2-1) + 2*3 => 2+6 = 8
  3*(3-1) + 3*7 => 6+21 = 27
  4*(4-1) + 4*5 => 12+20 = 32
  5*(5-1) + 5*8 => 20+40 = 60
  6*(6-1) + 6*7 => 30+42 = 72
  7*(7-1) + 7*8 => 42+56 = 98

  2+3--> 2*(3+1) = 2*4 = 8
  3+7--> 3*(7+2) = 3*9 = 27
  4+5--> 4*(5+3) = 4*8 = 32
  5+8--> 5*(8+4) = 5*12 = 60
  6+7--> 6*(7+5) = 6*12 = 72
  
  7+8--> 7*(8+6) = 7*14 = 98

• take 2+3
  2(1)+3(2)=2+6=8
  3(2)+7(3)=6+21=27
  lke that
  7(6)+8(7)=42+56=98
  is the ans

• 2+3 = 2*(3+1)=8
  3+7 = 3*(7+2)=27
  4+5 = 4*(5+3)=32
  i.e. first number is multiplied by sum of second number and (first number-1)
  hence, 6+7 = 6*(7+5)= 72
  similarly 7+8 = 7*(8+6) = 7*14 = 98ANS

• (2*3)+(2-1)=8
  Solution:-multiplt both the digits and u will find the product suppose X...then subtract the first digit by 1 and then multiply it by the original first digit....and the product obtained is suppose Y....and finally add both X+Y=answer
  Therefore the ans. Is 98
  (7*8)+[(7-1)7]=98

• ANSWER is 98;
  2*3+2=8; 3*7+6=27; 4*5+12=32; 5*8+20=60; 6*7+30=72;
  so the series of no. which is added is 2 ,6,12,20,30
  6-2=4; 12-6=6; 20-12=8; 30-20=10; x-30=12, x=42;
  so 7*8+42=98;
