Read Solution (Total 14)
-
- Ans: 7+2+5 = 143547
as in 5+3+2=151022
i) first no i.e. 5 multiply by second no i.e. 3 so (5 x 3 = 15)
ii)first no i.e. 5 multiply by third no i.e. 2 so (5 x 2 = 10)
iii) now first result no i.e. 15 + second result no 10 i.e. (15 + 10 = 25)
and now minus from this the middle no of equation i.e. 3(25-3 = 22)
solution wud b 151022
in this way (9x2=18)(9x4=36)(18+36=54)(54-2)=183652

- Answer (7*2) (7*5) (7(2+5)-2)=143568
Explanation
(5*3) (5*2) (5*(3+2)-3=15 10 22
(9*2) (9*4) (9*(2+4)-2=18 36 52
- 9 years agoHelpfull: Yes(1) No(0)
- 5*3 is 15
5*2 is 10
15 plus 10 is 25
25-3(middle number) is 22
that is 151022
similarly,
9*2 is 18
9*4 is 36
18 plus 36 is 54
54-2(middle number) is 52
that is 183654
similarly,
7*2 is 14
7*5 is 35
14 plus 35 is 49
49-2(middle number) is 57
answer is 143557 - 9 years agoHelpfull: Yes(1) No(0)
- answer is 143547.
14 and 35 is understood , 37 came
by
adding 14 and 35 and subtracting 2 the middle number.....
this is applicable on all the given expression

- 5+3+2= 15 10 22
For 15 =5×3 , for 10=5×2 ,,
For 22 = 15+10 -3(second digit)
Thus 7×2=14, 7×5=35 ,, 35+14-2=47
Ans is 7+2+5=143547 - 9 years agoHelpfull: Yes(0) No(0)
- 143547
7*2=14
7*5=35
14+35-5(middle no)=47 - 9 years agoHelpfull: Yes(0) No(0)
- 143545
7*2=12
7*5=35
12+35- 2 =45 - 9 years agoHelpfull: Yes(0) No(0)
- First four digit are to easy ,for last two digit,5*3+5*2 =25 from this we substract middle number "3" so that 25-3= 22 so we obtain. Last two digit. 9*2+9*4=54 and 54-2= 52 so 183652 and so on........
For 7+2+5=143547 , 7*2+7*5=49,49-2=47 - 8 years agoHelpfull: Yes(0) No(0)
- 5+3+2=151022
relation is
a+b+c=a*b[a*c][a*(b+c) - b]
5*3=15
5*2=10
5*(3+2) -2=22
digit is =151022
same concept applied on 7+2+5
7*2=14
7*5=35
7*(5+2) -2=47
digit is =143547
- 8 years agoHelpfull: Yes(0) No(0)
- 7*2=14
7*5=35
(14+35)-2=47
so ans is 143547 - 8 years agoHelpfull: Yes(0) No(0)
- 7 *2=14,7*5=35,7*(5+2)=49-2=47
Final ans. 143547 - 7 years agoHelpfull: Yes(0) No(0)
