Answer 2

Answer:

6)82,164 7)182 girls  8)150 coins

Step-by-step explanation:

6)Let the numbers be X And 2 X as other was twice of first

So, X+2 X= 246

3 X=246

X=246/3

X=82

Second =2 X=2*82 =164

7)Let the no of girls = X then boys = X+124

X+X+124=488

2 X=488-124

2 X=364

X= 364/2

X=182

So no of girls =182

8)So let the total no of coins be X

Rs. 75 can be written as 7500 paise

So 50* X=7500

X=7500/50

X=150

So, 150 Coins are in the piggy bank
