Question
Two circles of radii 15 cm and 10 cm touch each other
externally at a point A. PQ is the direct common tangent of those two circles of centers O β and O β respectively. The length of PQ is equal toSolution

- What will come in place of (?) in the given expression.
(β of 450) β (β of 300) = ? 62 + 43 + 625(1/4) - ? = 102
[564 + 32 of 18 Γ 9 Γ· 12 + 162 ] Γ· 4 = ?
?% of 740 β 8% of 650 = 7.2
Find the simplified value of the given expression.
{12.75 Γ β64 + 13.5 Γ β(β256)} Γ· 6 + 49.5 Γ· 5.5Β
- Simplify:
25% of [160% of (42 + 18) + 124] Γ· 66 Γ 150 What will come in the place of question mark (?) in the given expression?
? = 90% of 25% of (40 Γ 200) + 300
Simplify the expression and find the value of 'x'
35% of 500 of 18 Γ· 21 = x
236.23-653.23+696.23=?
(82 + 62 ) Γ 1.25 + 20% of 145 = ? β 40% of 65Β
