sonani patra  (10 years ago)

1.49,7,98,16,4,48,9,3
Divide it into 3 groups
(49,7,98),(16,4,48),(9,3,x)
Here 49*2=98
16*3=48
similarly 9*4=36 So x=36

(or)

7*(7)=49
7*(14)=98
And here (7*2)=14

4*(4)=16
4*(12)=48
And here (4*3=12)

Similarly,
3*(3)=9
3*(x)=36
And 3*(x i.e 4)=12

So result will be:
(9,3,x) i.e 3*12 = 36

RAHUL RANJAN  (9 years ago)

(49,7,98),(16,4,48),(9,3,x)
7^2=49 & 98/7= 14
4^2=16 & 48/4=12
3^2=9 & x/3=10
thus x=30

1. ans;- 36
(49,7,98),(16,4,48),(9,3,x)
Here 49*2=98
16*3=48
similarly 9*4=36 So x=36
2. ans:- (6^2,5^2) is similar to (5^1,*^1) so *is 4 because base reduce by 1 i.e 6 to 5,it is similar to 5 to 4 and power is same for first case but reduce by 1 in 2nd case
