Deviated from the plan by a bit.

RC: 16/17 (Source: OG 10)

Q107 The number of patents granted to inventors by the United States Patent Office dropped from 56,000 in 1971 to 45,000 in 1978. Spending on research and development, which peaked at 3 percent of the gross national product (GNP) in 1964, was only 2.2 percent of the GNP in 1978. During this period, when the United States percentage was steadily decreasing, West Germany and Japan increased the percentage of their GNP’s spent on research and development to 3.2 percent and 1.6 percent, respectively. Which of the following conclusions is best supported by the information above?
(A) There is direct relationship between the size of a nation’s GNP and the number of inventions it produces.
(B) Japan and West Germany spent more money on research and development is directly related to the number of inventions patented in that nation.
(C) The amount of money a nation spends on research and development is directly relocated to the number of inventions patented in that nation.
(D) Between 1964 and 1978 the United States consistently spent a larger percentage of its GNP on research and development than did Japan.
(E) Both West Germany and Japan will soon surpass the United States in the number of patents granted to investors.

DS: 16/17 (OG 10), 44/49 (Scoretop DS Collection : GMAT Data Sufficiency Sections 1-42)

OG was okay. Did not do very well on the scoretop questions, which were on the tougher side of the scale. Messed up about 3 questions because of not enough focus - a couple were genuine misses that I learnt from. My answer rate on these is a cause for worry - a lot of questions felt like 700+ questions (gut feel). I think I will add a scoretop section to each day that I practice DS - they seem to be good. May do the same for PS as well. Will try scoretop PS section(s) tomorrow.

Q If x and y are integers, is xy + 1 divisible by 3?
(1) When x is divided by 3, the remainder is 1.
(2) When y is divided by 9, the remainder is 8.

Q Rectangle ABCD is inscribed in a circle as shown above. What is the radius of the circle?
(1) The length of the rectangle is sqrt(3) and the width of the rectangle is 1.
(2) The length of arc AB (=length of rectangle) is of the circumference of the circle.



Q In the figure above, line AC represents a seesaw that is touching level ground at point A. If B is the midpoint of AC, how far above the ground is point C?
(1) x = 30
(2) Point B is 5 feet above the ground.

Q If b is an integer, is sqrt(a2 + b2) an integer?
(1) a2 + b2 is an integer.
(2) a2 – 3b2 = 0

RC:
Could not start on RC (2 passages), so that goes into backlog for tomorrow.
