- Consider LHS
As we have
(2+6+7)+9=24
(3+4+4)+29=40
(8+2+8)+55=73
similarly
(7+3+9)+87=106
Now Consider no.
9 then 29 then 55 then 87
Its series of difference 29 and 9 as 5×4+0=20
Then 55 and 29 as 5×5+1=26
Then 87 and 55 as 5×6+2=32 - 10 years agoHelpfull: Yes(20) No(34)
- As we have
(2+6+7)+9=24
(3+4+4)+29=40
(8+2+8)+55=73
29-9=20
55-29=26
x-55=32 coz 20, 26, so 32 next 38 and so on
x=87
hence (7+3+9)+87=106 - 10 years agoHelpfull: Yes(18) No(2)

- s we have
(2+6+7)+9=24
(3+4+4)+29=40
(8+2+8)+55=73
29-9=20
55-29=26
x-55=32 coz 20, 26, so 32 next 38 and so on
x=87
hence (7+3+9)+87=106.

- here we have
(2+6+7)+9=24
(3+4+4)+29=40
(8+2+8)+55=73
29-9=20
55-29=26
x-55=32 since 20, 26, so 32 next 38 and so on
x=87
therefore (7+3+9)+87=106

- first we need to find the value of 7,3,9
2+6+7=24,,from this we get 7=24-6-2 =>16
3+4+4=40,,from this we get 3=40-8=>32
2+6+7=24,,from this we get 7+2=24-6=>18
then ....
7+3+9=66 - 9 years agoHelpfull: Yes(2) No(1)
- Rakes:please explain clearly i am not understand

- 2*6=12 take 2nd digit 2 and 7*6=42 take 1st digit 4 so 24
8*2=16 take 6+1=7 ad 8*2=16 take 1+2=3 so 73
3*4=12 take 2+2=4 and 4*4=16 take 6+4=10 take 0(this pART IS A BIT ILLOGICAL...SORRY)
so 7*3=21 take 2+3=5 and 9*3=27 so take 7+6=13 take 3 so ans is 53 in my opinion

- (2+6+7)+9=24
(3+4+4)+29=40
(8+2+8)+55=73
29-9=20
55-29=26
x-55=32 coz 20, 26, so 32 next 38 and so on
x=87
hence (7+3+9)+87=106
