Steps: ek leti aur ek khadi line banao. Neeche groups ko barabar gap se likho. Same chaudai ke bars banao. Khadi line ke liye scale chuno, 0 se shuru karke.

Meher ka parivaar har mahine kiraye par ₹3,600, khaane par ₹4,200, school par ₹900, bijli par ₹600, aana-jaana par ₹1,200 aur baaki cheezon par ₹1,500 kharch karta hai. 1 unit = ₹300 lekar, har bar ki oonchaai ke liye bhaag do.

Graph se scale nikaalna: school canteen ne Somvaar ko 18 sandwich beche, aur Somvaar ka bar 6 units ooncha hai. To scale 18 ÷ 6 = 3 sandwich har unit hai. Phir Shukravaar ke 24 sandwich ke liye 8 units.

18 ÷ 6 = 3 · 24 ÷ 3 = 8

Explore: bar graphs banao. Bar chuno, phir kheencho ya buttons dabao.

1. Meher ke parivaar ka kharcha banao: kiraya 3,600, khaana 4,200, school 900, bijli 600, aana-jaana 1,200, baaki 1,500.
2. Zoya ne subah ki sair mein pakshi gine: goraiya 9, kauve 7, kabootar 10, maina 4, tote 3. Inhe banao (1 unit = 1).

Yaad rakho

• Bar ki oonchaai = number ÷ scale. Scale 0 se shuru hona chahiye.
• Aisa scale chuno ki graph achchhe se fit ho: na bahut lamba, na bahut chhota.

Quick check

Scale: 1 unit = ₹300. ₹1,800 ka bar kitna ooncha hoga?

1. 6 units
2. 18 units
3. 60 units
4. 3 units

Socho

Meher ke graph mein, kya bijli ka kharcha khaane ke kharche ke paanchve hisse se kam hai?
