Question
A and B together can finish a job in 12 days. B alone
takes 30 days. How long will A and C together take to finish the same job if C does one-fourth of A’s work?Solution
ATQ,
Work rates: A + B = 1/12 B = 1/30 So A = 1/12 – 1/30 = (5 – 2)/60 = 3/60 = 1/20 C = 1/4 of A = 1/80 A + C = 1/20 + 1/80 = (4 + 1)/80 = 5/80 = 1/16 Hence, 16 days
What is (0.08% of 0.008% of 8)1/9 ?
72 x 60 x 22 x 32 =?
641.5 + 72 × 8 = ? × 4
? = 6.25% of 240 + 252 + 172 – 16 × 17
∛21952 × 44 = ? × 14
(33 + 6.25% of 4096) = ? + 2 × 119
- What will come in the place of question mark (?) in the given expression?
62.5% of 120 + ? = (720 + 90) ÷ √36 Simplify the expression and find the value of 'x'
35% of 500 of 18 ÷ 21 = x
What will come in the place of question mark (?) in the given expression?
24% of 350 + 246 = ? + 50 × 2.5
(23 × 8) – (13 × 5) + 67 =? x 6         Â
