Let the pages read on first day be X, so then the pages read on next three days become X+20, X+40, X+60 respectively. Sum = X + X+20 + X+40 + X+60 = 4X + 120 = 4*(X + 30). This is equal to 208 given. So X+30 = 52 or X=22.

Hence B answer

Ans: B
We can also solve this as an arithmetic progression.
Total 208 of an AP with d=20 n=4 need to find the first term.
Total = (n/2)[2a+(n-1)d] ; 208 = (4/2)[2a+ (4-1)20]
solve this and a = 22

Above question can be done by two methods

I)X+20, X+40, X+60 respectively. Sum = X + X+20 + X+40 + X+60 = 4X + 120 = 4*(X + 30)=208

So X+30 = 52 or X=22

II)Total 208 of an AP with d=20 n=4 need to find the first term.
Total = (n/2)[2a+(n-1)d] ; 208 = (4/2)[2a+ (4-1)20]
solve this and a = 22

Give kudos if it helps

Since Rose reads the novel in 4 days and the pages she reads increase by 20 every day,
4 * (units digit of the number of pages she reads on the first day) = 8

Only Option B(22) remains and is our answer!

Let’s let x = the number of pages that Rose read on the first day. We see that (x + 20) is the number of pages she read on the second day; similarly, (x + 40) and (x + 60) are the numbers of pages she read on the 3rd and 4th days, respectively. We can then create the equation:

x + x + 20 + x + 40 + x + 60 = 208

4x = 88

x = 22
