Question

Part (ii) of the question please explain in detail
please anyone help! ​

Answer 1

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

Ist part se mean iska 43.68 aaya hoga jitna mujhe yaad haii..

Second part me humme mean 45 ke equal lene ke liye bola gya hai...

So ,

• New mean = 45

No. of matchsticks = Mean × No. of boxes

⟹ 45 × 50

⟹ 2250

Now extra match sticks required = 2250 - 2184

⟹ 66

2184 frequency ko add krne pe aaya haii jo ki purani matchbox ki matchsticks ka sum haii..
