PLEASE ANSWER DO NOT ANSWER IN UNITARY METHOD... IT'S A QUESTION OF DIRECT AND INVERSE VARIATION

Answer 1

Answer:

The food will last for 25 days

Step-by-step explanation:

500 - 30

100 more means

500+100= 600

Use the unitary method

500 : 30

600 : ? (But here thing is opposite that is more the people- less the days. So instead of cross multiplying we will do z multiplication)

500×30/600 (2 0s of 500 and 600 cancelled off)

= 5×30/6

= 150/6 = 25

Answer 2

Answer:

25 days

Step-by-step explanation:

For 500 men provision is for 30 days

now 100 more men join ...

i.e, 500+100 = 600

= 500 X 30 = 600 x (no. of days)

500 x 30/600 = no. of days

25 days
