213 to the nearest hundred = 200

∴ Required product = 500\times200=100000500×200=100000

(ii) 624\times236624×236

624 to the nearest hundred = 600 and,

236 to the nearest hundred = 200

∴ Required product = 600\times200=120000600×200=120000

(iii) 333\times247333×247

333 to the nearest hundred = 300 and,

247 to the nearest hundred = 200

∴ Required product = 300\times200=60000300×200=60000

(iv) 537\times283537×283

537 to the nearest hundred = 500 and,

283 to the nearest hundred = 300

∴ Required product =

500\times300=150000500×300=150000

(v) 382\times127382×127

382 to the nearest hundred = 400 and,

127 to the nearest hundred = 100

∴ Required product = 400\times100=40000400×100=40000

(vi) 427\times328427×328

472 to the nearest hundred = 500 and,
