Theoretically, adding water dosen't change dry density.
Hence, Yd is constant.
Hence, Yd is constant.

STEP 1. Y= 1.8/(1+0.05)
Y=1.71.
STEP 2. put y value in same formula,
1.71=x/(1+0.1),
X = 1.88.
(X is an unknown bulk density.)
Y=1.71.
STEP 2. put y value in same formula,
1.71=x/(1+0.1),
X = 1.88.
(X is an unknown bulk density.)

Please tell me how it is calculated?

For bulk density formula, further simplification we get;
(y2)/(y1) = (1+w2)/(1+w1),
=> y2/1.80 = (1+0.1)/(1+.05),
=>y2= 1.88.
(y2)/(y1) = (1+w2)/(1+w1),
=> y2/1.80 = (1+0.1)/(1+.05),
=>y2= 1.88.
