Answer 1

Answer: NO.OF APPLE RAVI HAD = 70

NO. OF APPLE RANI HAD = 50

Step-by-step explanation:

LET THE NUM,BER OF APPLE RAVI HAD BE x.

LET THE NUMBERE OF APPLES RANI HAD BE y.

A.T.P.

X+10=2(Y-10)

X+10=2Y-20

X=2Y-30------------------1

NOW,

X-10=Y+10

X=Y+20---------------------2

FROM EQN 1 AND 2,

2Y-30=Y+20

2Y-Y=30+20

Y=50

PUTTING THE VALUE OF Y IN EQN 2

X=20+50=70

HENCE, THE APPLE RAVI HAD= 70

APPLE RANI HAD = 50
