Solutions details
ANS - 1
Let the initial amount of milk in the jar be K.
Then, 972 = 
or, 
K = 4096 milliliters = 4.096 litres
ANS - 2
Let the present age of B be Q years
Then C = 30 + Q
Again, A + C = Q + 30
or, A = Q + 30 - Q - 8 = 22 years
ANS - 3
S.P. of 65% goods = 0.65x × 0.98 = 0.637x
S.P. of 65% goods = 0.35x × 0.16 = 0.406x
Total S.P. = 0.637x + 0.406x = 1.043x
.˙. Profit = 0.043x
Now, 0.043x = 1290
x =1290 / 0.043 = 30000

726 + 1296 - 22 = ? × 40
? × 40 = 2022 - 22
? = 50
ANS - 5
75% of 360 - 35 × 14 + 30% of 1250 = ?% of 500
270 - 490 + 375 = ? × 5
? = 155 ÷ 5
? = 31
ANS - 6
7 × 45 - 12 × 8 + 39 × 35 = ?
315 - 96 + 1365 = ?
? = 1680 - 96
? = 1584
ANS - 7
48.96 + 67.24 - 195.5 = ?
22.4 + ? = -79.3
? = -79.3 - 22.7
? = -102
