Answer:

The remaining food will last 10 days more according to the law of proportionality

Verified answer

Answer:

69

Step-by-step explanation:

remaining days : 88-7 = 81

hence

115 children eat in 81 days

135 children eat in y days

now here

children = 1/days

x = 1/y ( inverse propositions) x1 : x2:: y2: y1 ( compound ratio )

115 : 135:: y2 : 81

pro of extremes = pro of means

115 × 81= 135 ×y2

y2 = 115 ×81/ 135

y2 = 69
