88. Solve: 25 × 15625 = ?

Correct Answer: (1) 49
Solution:√(25 / 15625) = √(? / 30625)

⇒       5 / 125 = √(? / 175)

⇒       1 / 25 = √(? / 175)   ⇒   √? = 175 / 25 = 7

∴  ? = 7 × 7 = 49.

89. At a work site, a group of laborers undertakes a task planned for 8 hours, but 4 of them are absent. The remaining workers complete the task in 10 hours. How many workers were originally in the group?

Correct Answer: (2) 20
