Answer 1

Answer:

let he absent for x days

No. I of days for work=20days

payment=120/day

fine if will absent =10/day

Step-by-step explanation:

If work for it without absent =

$120 \times 20 = 2400$

total payment gained =1880rs

hence,

no. of absent fines=

$2400 - 1880 = 520$

but

fine per day =10

hence he absent for 52 days

Answer 2

Answer:

let he was absent for x days.

A/q,

120(20-x)-10x = 1880

2400-120x-10x = 1880

520x = 130x

x = 4 days ... (Ans)

यहां पर कुछ पहले अब टोटल value nikal Kar Kar rahe the,

see usse bhe aa jyga but agar aap ye maan rahe ho ki he was present for all 20 days , tab ye bhe to maano ki he was absent for all 20 days and fir alligation lagao ..

Let he was present for all 20 days .

than he would earn = 20*120 = 2400

and if he was absent for all 20 days ,

he loose = 20*10 = -200

now, by alliagtion rule ::--------

2400 -200

1880

(1880-(-200) :(2400-1880)

= 2080:520

= 4:1

so, he was present for = 20*4/5 = 16 days .

and absent for = 20*1/5 = 4 days (Ans)
