Nomendra Sinha  (9 years ago)

A+B=132
B+C=130---eq1
C+D=102---eq2
B+D=116---eq3
by solving eq1,2 &3
D=44 kg

Is this solution Helpfull? Yes (13) | No   

kalpana kumari  (9 years ago)

A+B=132...............eq1
B+C=130..........eq2
C+D=102.........eq3
B+D=116............eq4
then add eq3+eq4
B+C+2D=218
THEN PUT THE VALUE OE B+C GET D=44

Is this solution Helpfull? Yes (5) | No   

MUNISH YADAV  (9 years ago)

A+B=132
B+C=130
C+D=102
B+D=116
Subtract (3) from (4) we get B-D=28. Subtract this from (4) we get D=44.

A+B=132;----(1)
B+C=130;-----(2)
C+D=102;-----(3)
B+D=116;------(4)
FROM 3-- C=102-D AND FROM 4 -- B=116-D
SUB IN EQ 2
B+C=130 THAT IS
116-D+102-D=130;
218-2D=130;
2D=218-130;
2D=88;
D=44;
SO DINESH AGE IS 44

Rikhil Parashar  (9 years ago)

A+B=132
B+C=130
C+D=102
B+D=116
now...
B+C+C+D+B+D=130+102+116
2(B+C+D)=348
=> B+C+D=174
And we know that B+C=130
therefore,
D=174-130
D=44 option a)

Is this solution Helpfull? Yes (1) | No   

ABHINAV DINGRE  (9 years ago)

a+b=132, b+c=130, c+d=102, b+d=116
hence d=44

Is this solution Helpfull? Yes | No   

sindhureddy  (9 years ago)

a+b=132->1
b+c=130->2
c+d=102->3
b+d=116->4
solving 2,4 we get c-d value
solve it with equati0n 3
we get d as 44

Is this solution Helpfull? Yes | No   

Dwarsala lakshmi nikitha  (9 years ago)

Akhilesh+Bernard=132 ->1
Bernard+Catherine=130 ->2
Catherine+Dinesh=102 ->3
Bernard+Dinesh=116 ->4
by substitute method and solving equations 1,2,3 & 4
we get dinesh weight is 44kg
ans:a
