Answer:
280 men can build the house in 45 days.
Step-by-step explanation:
210 men can build a house in 60 days
1 Man can build the house in 60×210 days
By condition,
He was joined by 70 more men. Therefore, total men is 210+70=280 men.
280 men can build the house in 60×210/280
= 60×21/28
= 60×3/4
= 15×3 = 45(ans)
