Look at the equations and find the value of the missing number in the last equation of this riddle. If 1 + 4 = 5 2 + 5 = 12 3 + 6 = 21 Then 8 + 11 = ?
1+4=(1*4)+1=4+1=5 2+5=(2*5)+2=10+2=12 3+6=(3*6)+3=18+3=21 then 8+11=(8*11)+8=88+8=96 Ans:96
The answer is 96
Solution method 1 :- 1 + 4 = 5 2 + 5 = 12 7 is added to 5 to get the answer of the second addition which is 12. 3 + 6 = 21 Next odd number after 7 which is 9 is added to 12 to get the answer of the third addition 21. 4 + 7 = 32 (Next odd number after 9 which is 11 is added to 21 to get the next total.) 5 + 8 = 45 (Next odd number after 11 which is 13 is added to 32 to get the next total.) 6 + 9 = 60 (Next odd number after 13 which is 15 is added to 45 to get the next total.) 7 + 10 = 77 (Next odd number after 15 which is 17 is added to 60 to get the next total.) 8 + 11 = 96 (Next odd number after 17 which is 19 is added to 77 to get the next total.) So answer is 96. Solution method 2 :- 1 + 4 = 5 2 + 5 = 7 + previous total = 7 + 5 = 12 3 + 6 = 9 + previous total = 9 + 12 = 21 4 + 7 = 11 + previous total = 11 + 21 = 32 5 + 8 = 13 + previous total = 13 + 32 = 45 6 + 9 = 15 + previous total = 15 + 45 = 60 7 + 10 = 17 + previous total = 17 + 60 = 77 8 + 11 = 19 + previous total = 19 + 77 = 96 So answer is 96
Look at the table and find the connection between the numbers and find the value of the missing number in the table.
432 975 543 234 579 345 123 ? 345
